Scleroprotein

(also albuminoid), a simple protein of animal origin that is insoluble in water and in dilute solutions of salts, acids, and bases. The most important scleroproteins are collagen, keratin, and fibroin. All scleroproteins have a fibrillar structure. When present in organisms in solid or plastic state, scleroproteins ensure the mechanical firmness of organs, protect the organs from effects of the environment, and form supportive reticulate structures within cells and membranes, influencing the permeability of the latter. In the natural state, scleroproteins (except elastin) are not hydrolyzed by proteolytic enzymes and therefore have no nutritive value.

Other examples of scleroproteins are reticulin, which is found in the skin of mammals, the proteins of byssus and gossamer, flagellin (in the flagella of thermophile bacteria), conchiolin (in the shells of bivalve mollusks), iodine-containing spongin (in marine sponges), and gorgonin and antipathin (in corals).
