Sclerotin

High Quality Content by WIKIPEDIA articles! Sclerotin is a component of the cuticles of various Arthropoda, most particularly insects. It is formed by cross-linking members of particular classes of protein molecules, a biochemical process called sclerotization, but technically. The resulting material adds physical stiffness to the toughness of an insect's chitinous exoskeleton. It is particularly prominent in the thicker, armoured parts of insect and Arachnid integument, such as in the biting mouthparts and sclerites of scorpions and beetles.
