Which vitamin is essential for collagen formation in connective tissue?

• A. Vitamin D
• B. Vitamin B12
• C. Vitamin C
• D. Vitamin K

Answer: (C)

Vitamin C plays a crucial role in the synthesis of collagen, which is an essential protein found in connective tissues, including tendons, ligaments, and skin. It is a cofactor for enzymes involved in the hydroxylation of proline and lysine residues in collagen precursors, processes that are vital for the stability and strength of the collagen structure. Without sufficient vitamin C, collagen synthesis is impaired, leading to conditions such as scurvy, which is characterized by weakened connective tissues and various health issues. This connection between vitamin C and collagen formation underscores its importance in maintaining the integrity and functionality of various tissues in the body.
