Kev piav qhia: lyase yog cov chav kawm ntawm cov enzymes uas tsis cuam tshuam nrog hydrolysis lossis oxidation los rhuav tshem daim ntawv cog lus. Nws catalyzes kev tawg ntawm c-c, c-o, c-n, c-s daim ntawv cog lus los ntawm cov txheej txheem ntawm kev tshem tawm thiab ua rau muaj kev tsim ntawm ob daim ntawv cog lus.
Cov tshuaj tiv thaiv dab tsi yog catalyzed los ntawm Lyases?
Hauv biochemistry, lyase yog ib qho enzyme uas ua rau lub tawg (kev tshem tawm cov tshuaj tiv thaiv) ntawm ntau yam tshuaj sib cog lus los ntawm txhais tau tiasuas tsis yog hydrolysis (ib qho tshuaj hloov pauv) thiab oxidation, feem ntau tsim ib tug tshiab ob daim ntawv cog lus los yog ib tug tshiab nplhaib qauv. Cov tshuaj tiv thaiv rov qab kuj ua tau (hu ua Michael cov tshuaj tiv thaiv).
Qhov twg ntawm cov enzymes hauv qab no yog ib qho piv txwv ntawm Lyases?
Ib co piv txwv ntawm lyase suav nrog phenylalanine ammonia lyase, citrate lyase, isocitrate lyase, hydroxynitrile, pectate lyase, argininosuccinate lyase, pyruvate formate lyase, alginate lyase, thiab pectin.
Lias cov piv txwv yog dab tsi?
Lyase, hauv physiology, txhua tus tswv cuab ntawm chav kawm ntawm cov enzymes uas catalyze ntxiv lossis tshem tawm cov ntsiab lus ntawm dej (hydrogen, oxygen), ammonia (nitrogen, hydrogen), lossis carbon dioxide (carbon, oxygen) ntawm ob daim ntawv cog lus. Piv txwv li, decarboxylases tshem tawm carbon dioxide ntawm cov amino acids thiab dehydrases tshem dej.
Qhov twg ntawm cov tshuaj tiv thaiv hauv qab no yog catalyzed los ntawm enzyme m altase?
M altase enzyme catalyze hloov pauv ntawm m altose rau hauvqabzib (2 moles).
