- 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.

Historical Examples of collagen
By boiling with water, dilute acids or dilute alkalies, collagen is split up into gelatin or glutin.Principles and Practice of Fur Dressing and Fur Dyeing
William E. Austin
As goatskins are so tight fibred, a longer liming and a greater loss of collagen is permissible than with most pelts for chrome.Animal Proteins

- a fibrous scleroprotein of connective tissue and bones that is rich in glycine and proline and yields gelatine on boiling
Word Origin for collagen
Word Origin and History for collagen
structural protein of connective tissue, 1843, from French collagène, from Greek kolla "glue" + -gen "giving birth to" (see -gen).
- 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.
