[kol-uh-juh n] /ˈkɒl ə dʒən/
any of a class of extracellular proteins abundant in higher animals, especially in the skin, bone, cartilage, tendon, and teeth, forming strong insoluble fibers and serving as connective tissue between cells, yielding gelatin when denatured by boiling.
a fibrous scleroprotein of connective tissue and bones that is rich in glycine and proline and yields gelatine on boiling
structural protein of connective tissue, 1843, from French collagène, from Greek kolla “glue” + -gen “giving birth to” (see -gen).
collagen col·la·gen (kŏl’ə-jən)
The fibrous protein constituent of bone, cartilage, tendon, and other connective tissue that converts into gelatin by boiling.
Any of various tough, fibrous proteins found in bone, cartilage, skin, and other connective tissue. Collagens have great tensile strength, and provide these body structures with the ability to withstand forces that stretch them. Collagens consist of three polypeptide chains arranged in a triple helix, and are bundled together in fibers. When boiled in water, collagen is converted into gelatin.
collagenase col·lag·e·nase (kə-lāj’ə-nās’, -nāz’, kŏl’ə-jə-) n. Any of various enzymes that catalyze the hydrolysis of collagen and gelatin.
collagenation col·lag·e·na·tion (kə-lāj’ə-nā’shən, kŏl’ə-jə-) n.
noun, Pathology. 1. any of a group of diseases, as systemic lupus erythematosus, polyarteritis, scleroderma, and rheumatoid arthritis, involving inflammation or degeneration of connective tissue and accompanied by deposition of fibrinous material. collagen disease or collagen-vascular disease n. Any of a group of diseases affecting connective tissue and often characterized by fibrinoid necrosis or vasculitis […]
- Collagen fiber
collagen fiber or collagenous fiber n. An individual scleroprotein fiber composed of fibrils and usually arranged in branching bundles of indefinite length. Also called white fiber.
