Description and Uses
A non-essential amino acid. Can be isolated from gelatin. Hydroxyproline has not been reported as added to food in any of the NAS surveys.
A natural constituent of animal structural proteins such as collagen and elastin. Several microorganisms producing proline trans-4- and cis-3-hydroxylase were discovered and these enzymes were applied to the industrial production of trans-4- and cis-3-hydroxy-L-proline.
