D-Pyroglutamic acid C화학적 특성, 용도, 생산
개요
D-Pyroglutamic acid, also known as 5-oxo-D-proline, is a metabolite of D-glutamate. It is formed from D-glutamate by D-glutamate cyclase. The levels of D-pyroglutamic acid are increased in the urine of patients with nascent metabolic syndrome and the plasma of patients with end-stage renal disease.화학적 성질
white to light yellow crystal powder.정의
ChEBI: D-Pyroglutamic acid is the D-enantiomer of 5-oxoproline. It has a role as a metabolite. It is a D-proline derivative and a 5-oxoproline. It is a conjugate acid of a 5-oxo-D-prolinate. It is an enantiomer of a 5-oxo-L-proline.생물학적 활성
D-Pyroglutamic acid (PCA) is a cyclic derivative of glutamic acid, physiologically present in mammalian tissues. It has been shown that PCA releases GABA from the cerebral cortex and displays anti-anxiety effects in a simple approach-avoidance conflict situation in the rat. In clinical pharmacology experiments, PCA significantly shortens the plasma half-life of ethanol during acute intoxication.Purification Methods
Purify R-pyroglutamic acid by dissolving it in H2O, filtering, passing the filtrate through Dowex 50 (H+ form), washing with H2O, pooling washings, evaporating, removing H2O azeotropically with Me2CO and *C6H6, washing the residue with Et2O and recrystallising from EtOH/pet ether.
