DescriptionHydroxyproline is a neutral heterocyclic protein amino acid. It is found in collagen and as such it is common in many gelatin products. Hydroxyproline is mostly used as a diagnostic marker of bone turnover and liver fibrosis. Therapeutically, hydroxyproline is being studied as an an experimental medicine but is approved in France as a combination topical gel product called Cicactive for small, superficial wounds.
