L-Hydroxyproline is a common non-standard protein amino acid. As the main raw material of the antiviral drug atazanavir, it has high application value. L-Hydroxy Chemicalbook-based proline is generally used as a food additive (used as a sweetener in a relatively small amount), and used as a penem side chain intermediate in medicine in a relatively large amount.
