Puas pepsin tsis ua haujlwm hauv cov hnyuv?
Lub zog digestive ntawm pepsin yog qhov loj tshaj ntawm cov kua qaub ntawm cov kua qaub (pH 1.5-2.5). Nyob rau hauv txoj hnyuv, lub plab acids yog neutralized (pH 7), thiabpepsin tsis zoo lawm.
YPuas yog pepsin lossis trypsin hauv cov hnyuv?
Tus trypsinogen nkag mus rau hauv cov hnyuv me los ntawm cov kab mob sib xyaw thiab hloov mus rau nquag trypsin. Qhov no nquag trypsin ua nrog rau ob qho tseem ceeb digestive proteinases - pepsin thiab chymotrypsin - txhawm rau zom cov protein noj zaub mov rau hauv peptides thiab amino acids.
Puas muaj cov enzymes pom hauv cov hnyuv?
digestive enzymes feem ntau tsim nyob rau hauv pancreas, plab hnyuv, thiab cov hnyuv me. Tab sis txawm tias koj cov qog qaub ncaug tsim cov enzymes digestive kom pib zom cov zaub mov molecules thaum koj tseem zom.
