Kev Siv
Cholic acid yog ib qho metabolite uas muaj feem cuam tshuam nrog ob qho tib si tus tswv tsev thiab cov kab mob me me. Nws zoo li cov flakes tsis muaj xim lossis cov hmoov dawb crystalline. Nws tswj tus tswv tsev lub cev tiv thaiv kab mob thiab qhov virulence ntawm cov kab mob me me. Tom qab raug synthesized hauv tus tswv tsev, cholic acid raug secreted rau hauv txoj hnyuv, qhov twg cov kab mob me me tuaj yeem metabolize nws mus rau hauv ntau hom thawj thiab theem nrab cholic acids. Cov acids no tau pom tias ua lub luag haujlwm hauv tus tswv tsev lub cev tiv thaiv kab mob thiab cov haujlwm antibacterial.
Siv rau hauv kev tshawb fawb txog biochemical thiab ua ib qho tshuaj nruab nrab. Sodium cholate yog ib qho tshuaj uas txhawb nqa cov kua tsib, siv los kho cov mob xws li cholecystitis, bile deficiency, thiab plab hnyuv zom mov tsis zoo.
Ib qho organic acid nrog cov qauv steroid, uas tuaj yeem emulsify cov rog thiab txhim kho lawv cov nyhuv zom zaub mov.
Cov tshuaj ntxuav ionic uas tsis denaturing rau kev rho tawm cov protein membrane
Ib qho tshuaj ntxuav uas tsis yog ionic rau kev rho tawm cov protein membrane.
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.
