Which vitamin serves as a cofactor in collagen synthesis and acts as an antioxidant?

Vitamin C plays a crucial role in collagen synthesis and functions as a powerful antioxidant. In the context of collagen production, vitamin C is essential because it is a cofactor for the enzymes prolyl hydroxylase and lysyl hydroxylase, which are responsible for adding hydroxyl groups to proline and lysine residues in collagen. This hydroxylation is vital for the stability and cross-linking of collagen fibers, ensuring that the collagen formed has the structural integrity necessary for connective tissues.

Moreover, vitamin C’s antioxidant properties are significant as it helps protect cells from oxidative damage caused by free radicals. This dual role in both collagen synthesis and antioxidation makes vitamin C a unique and vital nutrient for maintaining healthy skin, blood vessels, and overall connective tissue health. The benefits of vitamin C in this regard underscore its importance in various biological processes, particularly in roles associated with growth, repair, and immune function.
