하이드록시프롤린 C화학적 특성, 용도, 생산

개요

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.

화학적 성질

White crystalline powder

용도

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.

용도

A versatile reagent for the synthesis of neuroexcitatory kainoids and antifungal echinocandins.

용도

hydroxyproline is a skin-conditioning amino acid. It is a component of collagen.

정의

ChEBI: An optically active form of 4-hydroxyproline having L-trans-configuration.

Purification Methods

Crystallise it from MeOH/EtOH (1:1). Separation from normal allo-isomer can be achieved by crystallisation of the copper salts [see Levine Biochemical Preparations 8 114 1961]. Separation from proline is achieved via the crystalline picrate, CdCl2, or acid ammonium rhodanate salts [see Greenstein & Winitz The Chemistry of the Amino Acids J. Wiley, Vol 3 p 2182 1961, Kapfhammer & Mohn Z Physiol Chem 306 76 1956]. [Beilstein 22/5 V 7.]
