Answer: A -Hydroxylase enzymes require vitamin C during collagen synthesis.
Explanation:
Vitamin C is essential for synthesis of collagen. Vitamin C is the essential cofactor for the two enzymes required for collagen synthesis which are prolyl hydroxylase (to stabilize the collagen molecule) and lysyl hydroxylase (to give structural strength cross-linking).
In addition to its antioxidant functions, vitamin C regulates the synthesis of the structural protein collagen. The role of vitamin C in the hydroxylation of collagen molecules is well characterized. Hydroxylation of collagen is necessary for its extracellular stability and support of the epidermis.
