  2. Collagen - Wikipedia

    en.wikipedia.org/wiki/Collagen

    Collagen is also abundant in corneas, 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 1% to 2% of muscle tissue and accounts for 6% of the weight to skeletal muscle. [4] The fibroblast is the most common cell creating collagen in ...

  3. Intermediate filament - Wikipedia

    en.wikipedia.org/wiki/Intermediate_filament

    Intermediate filaments (IFs) are cytoskeletal structural components found in the cells of vertebrates, and many invertebrates. [1] [2] [3] Homologues of the IF protein have been noted in an invertebrate, the cephalochordate Branchiostoma.

  5. Collagen helix - Wikipedia

    en.wikipedia.org/wiki/Collagen_helix

    TEM image of collagen fibres. In molecular biology, the collagen triple helix or type-2 helix is the main secondary structure of various types of fibrous collagen, including type I collagen. In 1954, Ramachandran & Kartha (13, 14) advanced a structure for the collagen triple helix on the basis of fiber diffraction data.

  6. Type I collagen - Wikipedia

    en.wikipedia.org/wiki/Type_I_collagen

    Type I collagen is the most abundant collagen of the human body, consisting of around 90% of the body's total collagen in vertebrates. Due to this, it is also the most abundant protein type found in all vertebrates. Type I forms large, eosinophilic fibers known as collagen fibers, which make up most of the rope-like dense connective tissue in ...

  7. Fibrous protein - Wikipedia

    en.wikipedia.org/wiki/Fibrous_protein

    A fibrous protein's peptide sequence often has limited residues with repeats; these can form unusual secondary structures, such as a collagen helix. The structures often feature cross-links between chains (e.g., cys-cys disulfide bonds between keratin chains). Fibrous proteins tend not to denature as easily as globular proteins.

  8. Type IV collagen - Wikipedia

    en.wikipedia.org/wiki/Type_IV_collagen

    Collagen IV (ColIV or Col4) is a type of collagen found primarily in the basal lamina. The collagen IV C4 domain at the C-terminus is not removed in post-translational processing, and the fibers link head-to-head, rather than in parallel. Also, collagen IV lacks the regular glycine in every third residue necessary for the tight, collagen helix ...

  9. Alpha collagen - Wikipedia

    en.wikipedia.org/wiki/Alpha_collagen

    Alpha collagen is designed to be used as a supplement for osteoarthritis, based on the theory of the different environments of the extracellular matrix (ECM). The ECM of joint cartilage comprises many classes of macromolecules; collagen (type I, II, VI, X collagen fibrils) and proteoglycans.
