Maltase zom maltose rau hauv qabzib. Sucrase zom cov sucrose (lossis "rooj qab zib") rau hauv qabzib thiab fructose, thiab lactase zom lactose (los yog "mis qab zib") rau hauv qabzib thiab galactose. Cov monosaccharides (piam thaj) yog li tsim tawm tau nqus thiab tom qab ntawd tuaj yeem siv rau hauv cov txheej txheem zom zaub mov kom siv lub zog.
Ib yam li ntawd, koj tuaj yeem nug, lub hom phiaj ntawm maltase yog dab tsi?
Maltase , enzyme uas catalyzes hydrolysis ntawm disaccharide maltose rau cov piam thaj yooj yim. Cov enzyme muaj nyob hauv cov nroj tsuag, kab mob, thiab cov poov xab; nyob rau hauv tib neeg thiab lwm yam vertebrates nws tau xav tias yuav tsum tau sib sau ua ke los ntawm cov cell ntawm cov qog ua kua hauv ob sab phlu hauv plab.
Qhov twg yog maltase sucrase thiab lactase tsim? Cov hnyuv Cov kab mob pancreatic tso rau hauv txoj hnyuv me kuj tseem muaj amylase uas zom cov hmoov txhuv nplej rau hauv disaccharide (ob lub suab thaj sib koom ua ke) hu ua maltose. Hauv cov hnyuv, enzymes xws li maltase thiab lactase zom cov disaccharides rau hauv cov suab thaj (monosaccharides), xws li qabzib.
Ib yam li ib tug yuav nug, Sucrase puas tuaj yeem rhuav tshem maltose?
Disaccharides yog tawg rau hauv cov suab thaj yooj yim thaum zom. Cov neeg muaj congenital sucrase -isomaltase deficiency tsis tuaj yeem ua tawg cov piam thaj sucrose thiab qab zib , thiab lwm yam sib xyaw ua los ntawm cov piam thaj molecules (carbohydrates).
maltase yog dab tsi?
Maltose yog ua los ntawm ob cov piam thaj molecules sib koom ua ke (1). Cov maltase enzyme yog cov protein uas ua tau zoo tshaj plaws los lees txais maltose molecule thiab rhuav tshem cov nyiaj (2). Ob qhov piam thaj molecules raug tso tawm (3).
