Nga korero taketake
proline oxidized te mohiotia hoki riteL-pyroglutamic waikawa. Papatipu rāpoi pātahi 129.12. Ko te ira whakarewa he 162-163 °c. Kaua e memeha i roto i te ether, te ethyl acetate-soluble, te whakarewa ki te wai (25 ° C 40), te waihano, te acetone me te waikawa acetic. Te hurihanga whatu motuhake -11.9 °(c = 2,H2O). Ka taea te whakamahi i tana tote konutai hei kai makuku i roto i nga mea whakapaipai, he pai ake te painga o te whakamakuku i te glycerol, te sorbitol, te kore-paitini, kaore he painga whakaongaonga, mo te tiaki kiri me nga whakapaipai makawe; Ko tenei hua he aukati i runga i te tyrosine oxidase, ka taea te aukati i te ahua o te melanin, he maamaa te kiri; He whakangohengohe ki te kiri, ka taea te whakamahi mo nga whakapaipai whao; Ka taea hoki te whakamahi hei surfactant mo te horoi; Reagents matū, mo te whakatau i nga amine racemic; takawaenga organic.
| Kupu Whakataki | Ko te waikawa pyroglutamic he 5-oxyproline. He mea hanga na te matewai i waenga i te roopu α-NH2 me te roopu γ-hydroxyl o te waikawa glutamic hei hanga i te herenga lactam ngota; Ka taea hoki te hanga ma te ngaro o te roopu Amido i roto i te ngota ngota glutamine. Mena he ngoikore te glutathione synthetase, ka puta pea te pyroglutamemia, he raupapa tohu tohu haumanu. Ko te Pyroglutamemia he mate o te paopaotanga waikawa waro na te ngoikoretanga o te glutathione synthetase. Nga whakaaturanga haumanu o te whanautanga 12 ~ 24 haora o te timatanga, hemolysis ahu whakamua, jaundice, ma'i Metabolic Acidosis, mate hinengaro, me etahi atu; Kei roto i te mimi te waikawa pyroglutamic, waikawa lactic, Alpha deoxy4 glycoloacetic acid lipid. Maimoatanga, tohumate, whakarongo ki te whakatika i te kai i muri i te tau. |
| taonga | Ko te waikawa L-pyroglutamic, e mohiotia ana ko te waikawa L-pyroglutamic, te waikawa L-pyroglutamic. Mai i te ewaro me te hinu etera ranunga i roto i te rerenga o te orthorhombic koeko rua Crystal, ira whakarewa o 162~163 ℃. Ka whakarewahia ki te wai, te waipiro, te acetone me te waikawa acetate, te ethyl acetate-soluble, kare e rewa i te etera. Te hurihanga whatu motuhake -11.9 °(c = 2,H2O). |
