L-Hydroxyproline
L-Hydroxyproline used to be isolated by hydrolysis of animal collagen, e. g. gelatin or collagen, of which it is a major constituent. L-Hydroxyproline is an unnatural amino acid which is made in the body by hydroxylation of L-Proline. The presence of L-Hydroxyproline is a key to maintaining the stability of the tight collagen helix. Today L-Hydroxyproline is manufactured by bio-catalyzed hydroxylation of proline in bacteria. Together with its other isomers, L-Hydroxyproline is widely used as an intermediate for a range of pharmaceutical active ingredients.
Yokobio’s L-Hydroxyproline is manufactured by fermentation and is non-animal sourced. Since L-Hydroxyproline derivatives are incorporated into the structure of the API, the purity of L-Hydroxyproline derivatives is critical. Yokobio’s L-Hydroxyproline is greater than 98.5 % pure. You can rely on our consistent quality. Yokobio can supply L-Hydroxyproline for your APIs in development and grow with you.
