Cov enzyme hauv tib neeg uas hloov sucrose rau piam thaj thiab fructose tau hu ua tiag sucrase , tab sis invertase tau siv vim tias nws pheej yig dua thiab yooj yim rau kev yuav.
Tsis tas li ntawd, ua li cas sucrose hloov pauv mus rau piam thaj thiab fructose?
Cov enzyme invertase (sucrase, saccharase) catalyzes hydrolysis ntawm qab zib (disaccharide) los ntxeev qab zib . Hloov qab zib yog 50/50 sib tov ntawm piam thaj thiab fructose -ob qho tib si monosaccharides. Poov xab tsis tuaj yeem ncaj qha metabolize (ferment) qab zib.
Qhov thib ob, ua li cas invertase zom cov sucrose? Invertase yog ib qho enzyme uas catalyzes cov hydrolysis ( tawg ) ntawm qab zib (rooj qab zib) rau hauv fructose thiab qabzib. Invertases thiab sucrases hydrolyze qab zib los muab tib qho sib xyaw ntawm cov piam thaj thiab fructose.
Yog li, puas yog Sucrose zoo ib yam li fructose?
Sucrose Ua los ntawm Glucose thiab Fructose hmoov Disaccharides yog ua los ntawm ob qho, txuas nrog monosaccharides thiab tawg rov qab mus rau tom kawg thaum lub sijhawm zom zaub mov (1). Sucrose yog disaccharide suav nrog ib qho qab zib thiab ib qho fructose qab zib molecule, lossis 50% qabzib thiab 50% fructose qab zib.
Cov enzyme twg yog siv hauv kev hloov pauv ntawm cov piam thaj qab zib?
Invertase

Cov enzyme twg yog lub luag haujlwm rau tshuaj zom cov hmoov txhuv nplej siab rau hauv cov piam thaj hauv tib neeg?
amylase Ib yam li ntawd, dab tsi enzymes koom nrog hauv kev zom cov hmoov txhuv nplej? Cov carbohydrates tau zom zom hauv lub qhov ncauj, plab thiab hnyuv me. Carbohydrase enzymes zom cov hmoov txhuv nplej siab rau hauv suab thaj. Cov qaub ncaug hauv koj lub qhov ncauj muaj amylase , uas yog lwm cov hmoov txhuv nplej siab zom zom enzyme.
Yam twg ntawm cov hauv qab no yog qhov hloov pauv hloov pauv tau rau kev mob pob txha?
Yam yuav hloov pauv tau yam muaj xws li: Dej cawv. Kev haus luam yeeb. Low Body Mass Index. Kev noj zaub mov tsis zoo. Vitamin D tsis txaus. Kev noj zaub mov tsis zoo. Estrogen tsis muaj peev xwm. Kev tawm dag zog tsis txaus
Yuav ua li cas hloov sucrose rau piam thaj thiab fructose?
Hauv tib neeg thiab lwm yam tsiaj, sucrose tau tawg rau hauv nws cov khoom sib xyaw monosaccharides, qabzib thiab fructose, los ntawm sucrase lossis isomaltase glycoside hydrolases, uas nyob hauv daim nyias nyias ntawm microvilli hauv ob sab hauv duodenum. Hauv cov kab mob thiab qee tus tsiaj, sucrose tau zom los ntawm cov enzyme invertase
Cov piam thaj thiab fructose tsim sucrose li cas?
Monosaccharides xws li cov piam thaj tuaj yeem txuas ua ke hauv kev sib xyaw ua ke. Piv txwv li, sucrose (tej suab thaj) yog tsim los ntawm ib qho molecule ntawm qabzib thiab ib qho ntawm fructose, raws li qhia hauv qab no. Molecules muaj ob lub monosaccharides hu ua disaccharides. Ib daim ntawv cog lus glycosidic tshuav ntawm ob lub monosaccharides
Yuav ua li cas sucrose ua los ntawm piam thaj thiab fructose?
Disaccharides: Sucrose tau tsim thaum lub monomer ntawm cov piam thaj thiab monomer ntawm fructose tau koom nrog hauv cov tshuaj tiv thaiv lub cev qhuav dej los tsim cov glycosidic bond. Hauv cov txheej txheem, ib qho dej molecule ploj lawm. Hauv sucrose, kev sib txuas glycosidic yog tsim los ntawm carbon 1 hauv qabzib thiab carbon 2 hauv fructose
