Signal peptides are cleaved inside the rer and the chains are now known as pro-alpha chains. Hydroxylation of lysine and proline amino acids occurs inside the lumen. This process is dependent on ascorbic acid (vitamin C) as a cofactor. Glycosylation of specific hydroxylysine residues occurs. Triple alpha helical structure is formed inside the endoplasmic reticulum from two alpha-1 chains and one alpha-2 chain. Procollagen is shipped to the golgi apparatus, where it is packaged and secreted by exocytosis. Outside the cell Registration peptides are cleaved and tropocollagen is formed by procollagen peptidase. Multiple tropocollagen molecules form collagen fibrils, via covalent cross-linking ( aldol reaction ) by lysyl oxidase which links hydroxylysine and lysine residues. Multiple collagen fibrils form into collagen fibers. Collagen may be attached to cell membranes via several types of protein, including fibronectin, laminin, fibulin and integrin. Synthetic pathogenesis edit vitamin C deficiency causes scurvy, a serious and painful disease in which defective collagen prevents the formation of strong connective shampoo tissue. Gums deteriorate and bleed, with loss of teeth; skin discolors, and wounds do not heal. Prior to the 18th century, this condition was notorious among long-duration military, particularly naval, expeditions during which participants were deprived of foods containing vitamin. An autoimmune disease such as lupus erythematosus or rheumatoid arthritis 34 may attack healthy collagen fibers.

Formation of the collagen fibril : lysyl oxidase, an extracellular copper-dependent enzyme, produces the final step in the collagen synthesis pathway. This enzyme acts on lysines and hydroxylysines producing aldehyde groups, which will eventually undergo covalent bonding between tropocollagen molecules. This polymer of tropocollogen is known as a collagen fibril. Amino acids edit collagen has an unusual amino acid composition and sequence: Glycine is found at almost every third residue. Proline makes up about 17 of collagen. Collagen contains two uncommon derivative amino acids not directly inserted during translation. These amino acids are found at specific locations relative to glycine and are modified post-translationally by different enzymes, both of which require vitamin c groeien as a cofactor. Cortisol stimulates degradation of (skin) collagen into amino acids. 33 Collagen I formation edit most collagen forms in a similar manner, but the following process is typical for type I: Inside the cell Two types of alpha chains are formed during translation on ribosomes along the rough endoplasmic reticulum (rer alpha-1 and alpha-2 chains. These peptide chains (known as preprocollagen ) have registration peptides on each end and a signal peptide. Polypeptide chains are released into the lumen of the rer.

lack of hydroxylation of prolines and lysines causes a looser triple helix (which is formed by three alpha peptides). Glycosylation occurs by adding either glucose or galactose monomers onto the hydroxyl groups that were placed onto lysines, but not on prolines. Once these modifications have taken place, three of the hydroxylated and glycosylated propeptides twist into a triple helix forming procollagen. Procollagen still has unwound ends, which will be later trimmed. At this point, the procollagen is packaged into a transfer vesicle destined for the golgi apparatus. Golgi apparatus modification : In the golgi apparatus, the procollagen goes through one last post-translational modification before being secreted out of the cell. In this step, oligosaccharides (not monosaccharides as in step 3) are added, and then the procollagen is packaged into a secretory vesicle destined for the extracellular space. Formation of tropocollagen : Once outside the cell, membrane bound enzymes known as 'collagen peptidases remove the "loose ends" of the procollagen molecule. What is left is known as tropocollagen. Defects in this step produce one of the many collagenopathies known as Ehlers-Danlos syndrome. This step is absent when synthesizing type iii, a type of fibrilar collagen.

Meshwork collagen, which is often involved in the formation of filtration systems, is the other form of collagen. All types of collagens are triple helices, and the differences lie in the make-up of the alpha peptides created in step. Transcription of mrna : About 34 genes are associated with collagen formation, each coding for a specific mrna sequence, and typically have the " verliefd col " prefix. The beginning of collagen synthesis begins with turning on genes which are associated with the formation of a particular alpha peptide (typically alpha 1, 2 or 3). Pre-pro-peptide formation : Once the final mrna exits from the cell nucleus and enters into the cytoplasm, it links with the ribosomal subunits and the process of translation occurs. The early/first part fashion of the new peptide is known as the signal sequence. The signal sequence on the n-terminal of the peptide is recognized by a signal recognition particle on the endoplasmic reticulum, which will be responsible for directing the pre-pro-peptide into the endoplasmic reticulum. Therefore, once the synthesis of new peptide is finished, it goes directly into the endoplasmic reticulum for post-translational processing. It is now known as pre-pro-collagen. Pre-pro-peptide to pro-collagen : Three modifications of the pre-pro-peptide occur leading to the formation of the alpha peptide: The signal peptide on the n-terminal is dissolved, and the molecule is now known as propeptide (not procollagen).

29 Synthesis edit first, a three-dimensional stranded structure is assembled, with the amino acids glycine and proline as its principal components. This is not yet collagen but its precursor, procollagen. Procollagen is then modified by the addition of hydroxyl groups to the amino acids proline and lysine. This step is important for later glycosylation and the formation of the triple helix structure of collagen. Because the hydroxylase enzymes that perform these reactions require vitamin c as a cofactor, a long-term deficiency in this vitamin results in impaired collagen synthesis and scurvy. 30 These hydroxylation reactions are catalyzed by two different enzymes: prolyl-4-hydroxylase 31 and lysyl-hydroxylase. Vitamin c also serves with them in inducing these reactions. In this service, one molecule of vitamin c is destroyed for each H replaced. 32 The synthesis of collagen occurs inside and outside of the cell. The formation of collagen which results in fibrillary collagen (most common form) is discussed here.

As a supplement edit When hydrolyzed, collagen is reduced to small peptides which can be ingested in the form of dietary supplement or functional foods and beverages with intent to aid joint and bone health and enhance skin health. Hydrolyzed collagen has a much smaller molecular weight in comparison to native collagen or gelatin, study suggests that more than 90 of hydrolyzed collagen is digested and available as small peptides in the blood stream within one hour. From the blood the peptides (containing hydroxyproline ) are transported into the target tissues,. Skin, bones and cartilage, where the peptides act as building blocks for local cells and help boost the production of new collagen fibers. Basic research edit collagen is used in laboratory studies for cell culture, studying cell behavior and cellular interactions with the extracellular environment. 26 Veterinary use edit some studies have shown efficacy of collagen supplementation for dogs with osteoarthritis pain, alone or in combination with other nutraceuticals like glucosamine and chondroitin. 27 28 Chemistry edit The collagen protein is composed of a triple helix, which generally consists of two identical chains (α1) and an additional chain that differs slightly in its chemical composition (α2). 29 The amino acid composition of collagen is atypical for proteins, particularly with respect to its high hydroxyproline content. The most common motifs in the amino acid sequence of collagen are glycine - proline -x and glycine-x-hydroxyproline, where x is any amino acid other than glycine, proline or hydroxyproline. The average amino acid composition for fish and mammal skin is given.

14 When collagen is made available to the wound bed, closure can occur. Wound deterioration, followed sometimes by procedures such as amputation, can thus be avoided. Collagen is a natural product, therefore it is used as a natural wound dressing and has properties that artificial wound dressings do not have. It is resistant against bacteria, which is of vital importance in a wound dressing. It helps to keep the wound sterile, because of its natural ability to fight infection. When collagen is used as a burn dressing, healthy granulation tissue is able to form very quickly over the burn, helping it to heal rapidly. 15 Throughout the 4 phases of wound healing, collagen performs the following functions in wound healing: guiding function: Collagen fibers serve to guide fibroblasts. Fibroblasts migrate along a connective tissue matrix. Chemotactic properties: The large surface area available on collagen fibers can attract fibrogenic cells which help in healing. Nucleation: Collagen, in the presence of certain neutral salt molecules can act as a nucleating agent brengen causing formation of fibrillar structures. A collagen wound dressing might serve as a guide for orienting new collagen deposition and capillary growth. Hemostatic properties: Blood platelets interact with the collagen to make a hemostatic plug. crystal collagen hair treatment

Most medical collagen is derived from young beef cattle (bovine) from certified bse -free animals. Most manufacturers use donor animals from either "closed herds or from countries which have never had a reported case of bse such as Australia, brazil, and New cold zealand. Bone grafts edit As the skeleton forms the structure of the body, it is vital that it maintains its strength, even after breaks and injuries. Collagen is used in bone grafting as it has a triple helical structure, making it a very strong molecule. It is ideal for use in bones, as it does organic not compromise the structural integrity of the skeleton. The triple helical structure of collagen prevents it from being broken down by enzymes, it enables adhesiveness of cells and it is important for the proper assembly of the extracellular matrix. 10 Tissue regeneration edit collagen scaffolds are used in tissue regeneration, whether in sponges, thin sheets, or gels. Collagen has the correct properties for tissue regeneration such as pore structure, permeability, hydrophilicity and it is stable in vivo. Collagen scaffolds are also ideal for the deposition of cells, such as osteoblasts and fibroblasts and once inserted, growth is able to continue as normal in the tissue. 11 Reconstructive surgical uses edit collagens are widely employed in the construction of the artificial skin substitutes used in the management of severe burns and wounds. 12 13 These collagens may be derived from bovine, equine, porcine, or even human sources; and are sometimes used in combination with silicones, glycosaminoglycans, fibroblasts, growth factors and other substances. Wound care edit collagen is one of the bodys key natural resources and a component of skin tissue that can benefit all stages of the wound healing process.

The collagenous structure that divides the upper chambers of the heart from the lower chambers is an impermeable membrane that excludes both blood and electrical impulses through typical physiological means. With honden support from collagen, atrial fibrillation should never deteriorate to ventricular fibrillation. Collagen is layered in variable densities with cardiac muscle mass. The mass, distribution, age and density of collagen all contribute to the compliance required to move blood back and forth. Individual cardiac valvular leaflets are folded into shape by specialized collagen under variable pressure. Gradual calcium deposition within collagen occurs as a natural function of aging. Calcified points within collagen matrices show contrast in a moving display of blood and muscle, enabling methods of cardiac imaging technology to arrive at ratios essentially stating blood in ( cardiac input ) and blood out ( cardiac output ). Pathology of the collagen underpinning of the heart is understood within the category of connective tissue disease. Cosmetic surgery edit collagen has been widely used in cosmetic surgery, as a healing aid for burn patients for reconstruction of bone and a wide variety of dental, orthopedic, and surgical purposes. Both human and bovine collagen is widely used as dermal fillers for treatment of wrinkles and skin aging. 9 Some points of interest are: When used cosmetically, there is a chance of allergic reactions causing prolonged redness; however, this can be virtually eliminated by simple and inconspicuous patch testing prior to cosmetic use.

The name collagen comes from the Greek κόλα ( kólla meaning " glue and suffix -γέν, -gen, denoting "producing". 6 7 This refers to the compound's early use in the process of boiling the skin and tendons of horses and other animals to obtain glue. Contents Types of collagen edit collagen occurs in many places throughout the body. Over 90 of the collagen in the human body, however, is type. 8 so far, 28 types of collagen have been identified and described. They can be divided into several groups according to the structure they form: Fibrillar (Type i, ii, iii, v, xi) Non-fibrillar facit (Fibril Associated Collagens with Interrupted Triple helices) (Type ix, xii, xiv, xix, xxi) Short chain (Type viii, x) Basement membrane (Type iv) Multiplexin. Type geluk iv : forms basal lamina, the epithelium-secreted layer of the basement membrane. Type v : cell surfaces, hair and placenta medical uses edit cardiac applications edit The collagenous cardiac skeleton which includes the four heart valve rings, is histologically, elastically and uniquely bound to cardiac muscle. The cardiac skeleton also includes the separating septa of the heart chambers the interventricular safe septum and the atrioventricular septum. Collagen contribution to the measure of cardiac performance summarily represents a continuous torsional force opposed to the fluid mechanics of blood pressure emitted from the heart.

Tropocollagen molecule: three left-handed procollagens (red, green, blue) join to form a right-handed triple helical tropocollagen. Collagen /kɒlədʒɪn/ is the caviar main structural protein in the extracellular space in the various connective tissues in animal bodies. As the main component of connective tissue, it is the most abundant protein in mammals, 1 making up from 25 to 35 of the whole-body protein content. Collagen consists of amino acids wound together to form triple- helices to form of elongated fibrils. 2, it is mostly found in fibrous tissues such as tendons, ligaments and skin. Depending upon the degree of mineralization, collagen tissues may be rigid (bone cream compliant (tendon or have a gradient from rigid to compliant (cartilage). It is also abundant in corneas, cartilage, bones, blood vessels, the gut, intervertebral discs, and the dentin in teeth. 3, in muscle tissue, it serves as a major component of the endomysium. Collagen constitutes one to two percent of muscle tissue, and accounts for 6 of the weight of strong, tendinous muscles. 4, the fibroblast is the most common cell that creates collagen. Gelatin, which is used in food and industry, is collagen that has been irreversibly hydrolyzed. 5 Collagen also has many medical uses in treating complications of the bones and skin.

Collagen is an important protein of the body's connective tissue and is vital to hair's structure and health. As a person ages, the body produces less collagen. Hair can become dry, brittle and coarse, break easily or even fall out. Products containing collagen don't just work on the outside layers of the hair, they work all the way down to the scalp and the hair cuticles. Supplementing it in your hair care routine can help maintain the health of the follicles.
