collagen defined in 1951 year

collagen - collagen;
collagen - Fibrous protein, which on boiling yields gelatin. Forms intercellular fibres ('white fibres' of vertebrate connective tissue). One of principal skeletal substances, binding cells and tissues together, probably throughout the Metazoa. Fibres made of collagen have a high tensile strength (exemplified by tendon) but unlike elastin fibres have little reversible extensibility. Identifiable by a peculiar amino acid, hydroxyproline, which hardly occurs elsewhere in animals. Superficial cuticle of some invertebrates, e.g. earthworm, is a protein like collagen. Leather is tanned, i.e. fixed, collagen of dermis. See also: Fibroblast, Reticulin Fibres.
