Phenyl2,3,4,6-tetra-O-acetyl-1-thio-β-D-galactopyranoside CAS: 24404-53-3

Phenyl2,3,4,6-tetra-O-acetyl-1-thio-β-D-galactopyranoside feem ntau siv ua lub substrate rau cov enzyme β-galactosidase. Thaum β-galactosidase ua haujlwm rau nws, cov tshuaj no raug hydrolyzed, ua rau muaj p-nitrophenol lossis o-nitrophenol, uas muaj xim daj uas tuaj yeem pom tau yooj yim. Qhov no ua rau nws muaj txiaj ntsig zoo li lub substrate rau kev ntsuas uas ntsuas β-galactosidase kev ua haujlwm.

Ib qho kev siv Phenyl2,3,4,6-tetra-O-acetyl-1-thio-β-D-galactopyranoside feem ntau yog nyob rau hauv kev ntsuam xyuas cov noob caj noob ces. Hauv cov kev ntsuam xyuas no, ib lub noob caj noob ces uas xav paub ntxiv yog txuas nrog ib lub noob caj noob ces, xws li lub noob beta-galactosidase. Tom qab ntawd, kev ua haujlwm ntawm lub noob caj noob ces raug saib xyuas los ntawm kev ntsuas β-galactosidase kev ua haujlwm siv Phenyl2,3,4,6-tetra-O-acetyl-1-thio-β-D-galactopyranoside ua lub substrate. Qhov no tso cai rau cov kws tshawb fawb kawm txog kev qhia tawm thiab kev tswj hwm cov noob caj noob ces.

Phenyl2,3,4,6-tetra-O-acetyl-1-thio-β-D-galactopyranoside kuj tseem siv tau los tshuaj xyuas cov tshuaj inhibitors lossis activators ntawm β-galactosidase. Los ntawm kev sim cov tshuaj sib txawv lossis cov tshuaj sib txawv, cov kws tshawb fawb tuaj yeem txheeb xyuas cov molecules uas hloov pauv cov haujlwm ntawm cov enzyme no, uas tuaj yeem muaj kev siv kho mob hauv qee yam kab mob lossis mob.

Ntxiv mus, cov tshuaj no siv tau rau hauv kev ntxuav cov protein. β-galactosidase feem ntau yog sib xyaw nrog cov protein uas xav tau los pab txhawb lawv txoj kev tshawb pom thiab kev ntxuav. Phenyl2,3,4,6-tetra-O-acetyl-1-thio-β-D-galactopyranoside siv tau ua lub substrate los tshuaj xyuas thiab ntxuav cov protein sib xyaw no los ntawm kev kuaj pom cov haujlwm β-galactosidase.
