Ulwazi olusisiseko
proline oxidized ikwabizwa ngokubaI-L-pyroglutamic acid. Ubunzima bemolekyuli obunxulumeneyo 129.12. Indawo yokunyibilika yayiyi-162-163 °c. Musa ukunyibilika kwi-ether, i-ethyl acetate-soluble, i-soluble emanzini (25 ° C 40), i-ethanol, i-acetone kunye ne-acetic acid. Ukujikeleza okuthe ngqo kwe-optical -11.9 °(c = 2,H2O). Ityuwa yayo ye-sodium ingasetyenziselwa njenge-ejenti yokuthambisa kwi-cosmetics, umphumo wayo wokuthambisa ungcono kune-glycerol, i-sorbitol, i-non-toxic, akukho mpembelelo evuselelayo, ekunyamekelweni kwesikhumba kunye nezimonyo zokunakekelwa kweenwele; Le mveliso inefuthe lokuthintela kwi-tyrosine oxidase, inokuthintela ukubekwa kwe-melanin-efana, inefuthe elimhlophe eluswini; Inomphumo wokuthambisa eluswini, ingasetyenziselwa izithambiso zezikhonkwane; Isenokusetyenziswa njenge-surfactant kwizinto zokucoca; Ii-reagents zeMichiza, zokusombulula ii-amines zobuhlanga; Izinto eziphilayo.
| Intshayelelo | i-pyroglutamic acid yi-5-oxyproline. Yenziwe ngokuncipha kwamanzi phakathi kweqela le-α-NH2 kunye ne-γ-hydroxyl iqela le-glutamic acid ukwenza i-molecular lactam bond; Inokusekwa ngokulahlekelwa kweqela le-Amido kwi-molecule ye-glutamine. Ukuba ukusilela kwe-glutathione synthetase, kunokubangela i-pyroglutamemia, uthotho lweempawu zeklinikhi. I-Pyroglutamemia luphazamiseko lwe-organic acid metabolism olubangelwa kukunqongophala kwe-glutathione synthetase. Ukubonakaliswa kweklinikhi yokuzalwa kwe-12 ~ 24 iiyure zokuqala, i-hemolysis eqhubekayo, i-jaundice, i-Metabolic Acidosis engapheliyo, ukuphazamiseka kwengqondo, njl.; Umchamo uqukethe i-pyroglutamic acid, i-lactic acid, i-Alpha deoxy4 glycoloacetic acid lipid. Unyango, uphawu, nikela ingqalelo ukulungelelanisa ukutya emva kweminyaka yobudala. |
| iipropati | I-L-pyroglutamic acid, eyaziwa ngokuba yi-L-pyroglutamic acid, i-L-pyroglutamic acid. Ukusuka kumxube we-ethanol kunye ne-petroleum ether kwimvula ye-orthorhombic cone ephindwe kabini yeCrystal engenambala, indawo yokunyibilika ye-162 ~ 163 ℃. Inyibilika emanzini, utywala, i-acetone kunye ne-acetic acid, i-ethyl acetate-soluble, i-ether enganyibilikiyo. Ukujikeleza okuthe ngqo kwe-optical -11.9 °(c = 2,H2O). |
