scleroprotein

scleroprotein, large class of protein molecules that are ordinarily insoluble in water. The scleroproteins are employed principally for architectural purposes in the living cell and are localized in the structural tissues of bone, hair, skin, wool, silk, nails, hooves, and feathers. The major subclasses of scleroproteins include the collagens, elastins, and keratins.

scleroprotein

scleroprotein Any of a group of proteins found in the exoskeletons of some invertebrates, notably insects. Scleroproteins are formed by conversion of the relatively soft elastic larval protein by a natural tanning process (sclerotization) involving orthoquinones. These are secreted and form cross linkages between polypeptides of the proteins, producing a hard rigid covering.
