Raffinose tsev neeg ntawm oligosaccharides (RFOs) yog α-1, 6-galactosyl txuas ntxiv ntawm sucrose (Suc). Cov pab pawg no ntawm oligosaccharides pom muaj nyob rau hauv cov nroj tsuag thiab paub tias yog desiccation tiv thaiv nyob rau hauv cov noob, raws li thauj qab zib nyob rau hauv phloem SAP thiab raws li cia qab zib.
Dab tsi muaj raffinose?
Raffinose yog ib qho trisaccharide tsim los ntawm galactose, qabzib, thiab fructose. Nws tuaj yeem pom hauv taum, zaub qhwv, brussels sprouts, broccoli, asparagus, lwm yam zaub, thiab tag nrho cov nplej.
Raffinose yog dab tsi?
Raffinose yog a trisaccharide uas cov piam thaj ua haujlwm ua tus choj monosaccharide ntawm galactose thiab fructose. Nws muaj ob qho tib si α thiab β glycosidic bonds thiab tuaj yeem ua rau hydrolyzed rau d-galactose thiab sucrose ntawm enzymes nrog α-glycosidic kev ua, thiab rau melibiose thiab d-fructose ntawm enzymes nrog β-glycosidic kev ua.
Puas yog raffinose disaccharides?
D. none ntawm saum toj no. Lus Qhia: Raffinose muaj cov mis molecular C18H32O16 yog ib qho oligosaccharides uas muaj ntau dua ib chav tsev qab zib.
Dab tsi yog txoj haujlwm ntawm raffinose?
Dhau li ntawm a khaws cia thiab thauj daim ntawv carbohydrate, cov tswv cuab raffinose ua lub luag haujlwm hauv kev tiv thaiv kab mob abiotic. Cov raffinose tseem ceeb yog raffinose (trisaccharide) thiab stachyose (tetrasaccharide), tab sis ntau dua oligomers kuj muaj nyob rau hauv qee cov nroj tsuag.
