oxidized proline ua lauiloa foi oL-pyroglutamic acid. Masisa mole mole tutusa 129.12. O le liusuavai o le 162-163 °c. Aua ne'i solo i le eter, ethyl acetate-soluble, soluble i le vai (25 ° C 40), ethanol, acetone ma acetic acid. Ma'oti opitika fa'asolo -11.9 °(c = 2,H2O). O lona masima sodium e mafai ona faʻaaogaina e avea o se mea faʻafefete i mea teuteu, o lona faʻasusuina e sili atu nai lo le glycerol, sorbitol, leai se mea oona, leai se aafiaga faʻaosofia, mo le tausiga o le paʻu ma le tausiga o lauulu; O lenei oloa o loʻo i ai le faʻaogaina o le tyrosine oxidase, e mafai ona puipuia le tuʻuina atu o le melanin-pei, ei ai se aafiaga paʻepaʻe i luga o le paʻu; E i ai se aafiaga faʻamalulu i luga o le paʻu, e mafai ona faʻaogaina mo fao teuteu; E mafai foʻi ona faʻaaogaina e fai ma mea faʻafefe mo faʻamaʻi; Reagents vailaʻau, mo le fofo o amine racemic; Mea fa'aletino.

 

Folasaga pyroglutamic acid o le 5-oxyproline. E faia e ala i le fa'amama i le va o le α-NH2 vaega ma le γ-hydroxyl vaega o le glutamic acid e fausia ai se mole lactam bond; E mafai foi ona fausia e ala i le leiloa o se vaega Amido i se mole glutamine. Afai ole glutathione synthetase deficiency, e mafai ona mafua ai le pyroglutamemia, o se faasologa o faʻamaoniga ile falemaʻi. O le pyroglutamemia o se faʻafitauli o le metabolism o le acid organic e mafua mai i le glutathione synthetase deficiency. Faʻaaliga faʻapitoa o le fanau mai 12 ~ 24 itula o le amataga, hemolysis alualu i luma, jaundice, Metabolic Acidosis tumau, faaletonu o le mafaufau, ma isi; O le urine e iai le pyroglutamic acid, lactic acid, Alpha deoxy4 glycoloacetic acid lipid. Togafitiga, faʻailoga, faʻalogo lelei e fetuunai le meaʻai pe a uma le matua.
meatotino L-pyroglutamic acid, e lauiloa foi o le L-pyroglutamic acid, L-pyroglutamic acid. Mai le ethanol ma le suauu ether paluga i le timuga o colorless orthorhombic cone lua Crystal, liusuavai tulaga o 162 ~ 163 ℃. Solu i le vai, ava malosi, acetone ma acetic acid, ethyl acetate-soluble, e le mafai ona solu i le eter. Ma'oti opitika fa'asolo -11.9 °(c = 2,H2O).
