Kev Siv
Siv ua cov khoom siv rau kev kuaj mob transaminase thiab dehydrogenase, txhawb nqa cov tshuaj reagent rau kev kuaj mob siab, thiab nruab nrab hauv kev tsim cov organic.
Siv ua cov tshuaj reagent analytical rau tryptophan; substrate rau kev txiav txim siab ntawm transaminase thiab dehydrogenase; auxiliary reagent rau kev kuaj mob siab.
Ib qho derivative ntawm valeric acid, nws yog ib qho intermediate hauv Krebs voj voog catalyzed los ntawm glutamate dehydrogenase.
α-Ketoglutaric acid siv tau ua cov khoom siv raw rau cov tshuaj, cov khoom siv kho mob thiab cov khoom noj khoom haus ntxiv.
Ntim thiab Xa Khoom
25KG / Nruas los yog raws li cov neeg siv khoom xav tau.
Yog cov khoom siv dav dav thiab tuaj yeem xa los ntawm dej hiav txwv thiab huab cua
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
Lub tsev rau khoom muaj cua nkag, ziab kom qhuav kub tsawg, Sib cais ntawm cov tshuaj oxidants, cov kua qaub.
