Trypsin thiab chymotrypsin yog ib qho tseem ceeb digestive enzymes uas yog secreted los ntawm lub pancreas ua cov enzyme tsis ua haujlwm ua ntej trypsinogen thiab chymotrypsinogen. Trypsin qhib nws tus kheej los ntawm kev tawm tswv yim zoo thiab hloov chymotrypsinogen thiab lwm yam enzymes tsis ua haujlwm rau hauv lawv cov ntaub ntawv nquag.
YPuas yog chymotrypsin thiab trypsin tib yam?
Kev xaiv. Qhov sib txawv tseem ceeb ntawm chymotrypsin thiab trypsin yog cov amino acids lawv xaiv rau. Chymotrypsin yog cov enzyme uas xaiv rau cov amino acids uas muaj ntxhiab: phenylalanine, tryptophan, thiab tyrosine. Trypsin yog cov enzyme uas xaiv rau cov amino acids yooj yim: lysine thiab arginine.
YPuas yog chymotrypsin tsim los ntawm trypsin?
Chymotrypsin yog synthesized hauv pancreaslos ntawm cov protein biosynthesis ua tus precursor hu ua chymotrypsinogen uas yog enzymatically inactive. Trypsin activates chymotrypsinogen los ntawm cleaving peptidic bonds nyob rau hauv txoj hauj lwm Arg15 - Ile16 thiab tsim π-chymotrypsin.
YPuas yog trypsin thiab chymotrypsin lipases?
Tus exocrine pancreas zais peb qhov endopeptidases (trypsin, chymotrypsin, thiab elastase) thiab ob exopeptidases (carboxypeptidase A thiab carboxypeptidase B) inactive forms. Enterokinase ntawm txhuam ciam teb pib ib qho kev ua haujlwm ntawm pancreatic enzymes los ntawm kev hloov trypsinogen rau hauv trypsin.
Dab tsi ua rau trypsin thiab chymotrypsin?
Nws tau qhib rau hauv nws daim ntawv nquag los ntawm lwm cov enzyme hu ua trypsin Daim ntawv nquag no hu ua π-chymotrypsin thiab siv los tsim α-chymotrypsin. Trypsin cleaves peptide daim ntawv cog lus hauv chymotrypsinogen ntawm arginine-15 thiab isoleucine-16. … Cov tshuaj tiv thaiv no ua rau α-chymotrypsin.
