For each term select the description that best describes its contribution to the structure of collagen.
-Allysine
A)Forms covalent cross links

C)Required for hydroxylation
D)Allows tightly wound helix formation
E)Has H bonds which help stabilize the protein

Question

Quizplus · Accepted Answer

Allysine forms covalent cross links between collagen molecules, contributing to the strength and stability of collagen fibrils.

Answer: C 
 Hydroxylation of lysine and proline residues in collagen is dependent on the presence of allysine, as it is a required precursor for the enzyme responsible for hydroxylation.

Answer: D 
 Although allysine does not directly contribute to helix formation, the formation of covalent cross links via allysine between collagen molecules allows for the tightly wound triple helix structure characteristic of collagen.

Therefore, choices A, C, and D are the best options for describing allysine's contribution to the structure of collagen.
