Hauv biochemistry, lub substrate yog ib qho molecule uas ib qho enzyme ua. Enzymes catalyze tshuaj cov tshuaj tiv thaiv koom nrog substrate (s). Yog ib leeg xwb substrate , cov substrate kev sib txuas nrog lub enzyme active site, thiab ib qho enzyme- substrate complex yog tsim.
Ib yam li ntawd, tib neeg nug, piv txwv li substrate yog dab tsi?
A substrate yog ib yam khoom siv los yog nruab nrab uas lwm yam khoom siv tau siv thiab cov khoom thib ob adheres. Cov rog (butter), proteins (soybean), carbohydrates (qos yaj ywm) yog tag nrho substrate thiab ua raws li cov enzymes uas yog lipases, proteases thiab glycosidases.
Tsis tas li ntawd, yuav ua li cas thaum lub substrate txuas mus rau ib qho enzyme? Thaum ib enzyme khi nws substrate , nws forms enzyme - substrate complex. Qhov no tuaj yeem contort lub substrate molecules thiab pab txhawb kev sib koom ua ke. Lub active site ntawm ib enzyme kuj tsim ib qho chaw zoo tagnrho, xws li ib puag ncig acidic lossis tsis-polar, rau qhov tshwm sim.
Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog qhov substrate ntawm cov tshuaj tiv thaiv catalase?
Cov khoom uas ib enzyme ua thiab coj tawm kev hloov pauv yog hu ua substrate. Lub substrate rau catalase cov tshuaj tiv thaiv yog hydrogen peroxide.
Puas yog lub substrate puas yog reactant?
A substrate yog ib qho molecule uas ib qho enzyme ua. Cov substrate yog hloov los ntawm cov tshuaj tiv thaiv thiab, nyob rau hauv cov ntaub ntawv no, ob yam khoom yog ua. A reactant thiab substrate muaj tib lub ntsiab. Lub sij hawm reactant feem ntau siv hauv chemistry.
