Ascorbic acid aids in healing. Which of the following applies?

The statement that applies correctly to the role of ascorbic acid, or vitamin C, in healing relates to the process where proline is converted into hydroxyproline, which is a crucial step in collagen synthesis. Ascorbic acid acts as a co-factor for the enzymes that catalyze this conversion. Hydroxyproline is important for the stabilization and structural integrity of collagen.

Collagen is a major structural protein found in various connective tissues in the body, and its synthesis is vital for wound healing and tissue repair. Proline, an amino acid, is hydroxylated to form hydroxyproline, which is then incorporated into the collagen structure. Therefore, the sequence that starts with proline and ends with the formation of collagen through the intermediate, hydroxyproline, accurately describes the role of ascorbic acid in the healing process. This biological pathway is critical in ensuring that collagen is properly formed and functional, leading to effective tissue repair and healing.
