4-Nitrophenyl-alpha-D-galactopyranoside CAS: 7493-95-0

Cov khoom siv rau kev ntsuam xyuas enzymatic: 4-Nitrophenyl-alpha-D-glucopyranoside feem ntau yog siv ua cov khoom siv hauv kev ntsuam xyuas enzymatic los ntsuas qhov kev ua haujlwm ntawm glycosidases thiab lwm yam enzymes uas koom nrog hauv kev ua haujlwm ntawm carbohydrate. Cov enzymes no tuaj yeem txiav qhov sib txuas ntawm glucose thiab 4-nitrophenyl pawg, tso tawm cov khoom daj hu ua 4-nitrophenol. Qhov ntau ntawm 4-nitrophenol tsim tawm yog ncaj qha rau qhov kev ua haujlwm ntawm enzyme, uas tso cai rau kev ntsuas qhov ntau ntawm cov haujlwm enzyme.

Kev Tshawb Pom Kev Ua Haujlwm ntawm Cov Enzyme: Los ntawm kev siv 4-Nitrophenyl-alpha-D-glucopyranoside ua ib qho substrate, kev ua haujlwm ntawm cov enzymes tshwj xeeb tuaj yeem ntsuas tau. Piv txwv li, cov enzymes glycosidase xws li beta-glucosidase, alpha-glucosidase, lossis beta-galactosidase tuaj yeem txiav cov tshuaj, tso tawm 4-nitrophenol, uas tuaj yeem kuaj pom los ntawm photometrically. Txoj kev no siv dav hauv ntau yam kev kho mob, tshuaj, thiab biotechnological daim ntawv thov.

Kev tshuaj ntsuam xyuas siab: Vim nws sib xws nrog cov tshuab nrhiav tsis siv neeg, 4-Nitrophenyl-alpha-D-glucopyranoside feem ntau siv rau hauv kev tshuaj ntsuam xyuas siab. Cov tshuaj no tso cai rau kev piav qhia sai thiab ua haujlwm zoo ntawm cov enzyme ua haujlwm, ua rau nws muaj txiaj ntsig zoo hauv kev tshawb nrhiav tshuaj, kev tsim enzyme, thiab kev tshawb fawb txog kev txwv enzyme.

Cov ntawv thov kuaj mob: 4-Nitrophenyl-alpha-D-glucopyranoside siv tau rau hauv cov ntawv thov kuaj mob kom paub txog qhov muaj lossis kev ua haujlwm ntawm cov enzymes tshwj xeeb uas cuam tshuam nrog ntau yam kab mob. Piv txwv li, kev ua haujlwm ntawm qee cov enzymes tuaj yeem siv ua lub cim kuaj mob rau cov kab mob tshwj xeeb, thiab 4-Nitrophenyl-alpha-D-glucopyranoside tuaj yeem siv ua lub hauv paus los ntsuas kev ua haujlwm ntawm cov enzymes no hauv cov qauv kuaj mob.
