Vitamin C (ascorbic acid) is a water soluble vitamin that is a coenzyme for the formation of the structure protein collagen, particularly creating cross-linking of collagen fibres which greatly increases its tensile strength. It also acts as an antioxidant.
Pathological manifestations can occur both in excess and deficiency:
- hypervitaminosis C has not been observed, but the oxidised form of ascorbic acid can be toxic.
- hypovitaminosis C: scurvy
