Question

Quizplus · Accepted Answer

Lysine is involved in the cross-linking found in insoluble collagen. When collagen is formed, lysine and hydroxylysine residues are oxidized into reactive aldehydes. These aldehydes can react with the lysine or hydroxylysine residues on another collagen molecule, forming a covalent cross-link between the two molecules. This cross-linking is what gives collagen its strength and stability.
