D-glucose, D-fructose thiab D-mannose tsim tib yam osazone kho nrog ntau tshaj phenyl hydrazine vim lawv txawv tsuas yog 1st thiab 2nd carbon atoms uas hloov mus rau tib yam. form.
Yuav ua li cas osazone nrog phenylhydrazine?
GLUCOSE | Cov Khoom thiab Kev Ntsuam Xyuas
Phenyl hydrazine reactsnrog cov pawg carbonyl ntawm cov suab thaj, ua rau tsim cov phenylhydrazone thiab osazone (Daim duab 9).
Cov piam thaj twg hauv qab no tsim osazone nrog phenylhydrazine?
Galactose thiab Mannose yog epimers ntawm Glucose. Ua kom tiav cov kauj ruam los ntawm kev daws teeb meem: Osazones yog cov derivatives ntawm carbohydrates uas yog tsim los ntawm lawv cov tshuaj tiv thaiv nrog Phenylhydrazine.
Qhov twg ntawm cov carbohydrates hauv qab no muab tib yam osazone?
Qhov sib npaug ntawm reagent yog siv los oxidize hydroxyl pab pawg neeg carbonyl. Cov pawg uas nyob ib sab -CHOH yog oxidized. Yog li no, peb tuaj yeem hais tau tias aldose thiab ketose muaj tib lub osazone vim lawv muaj cov qauv zoo ib yam ntawm txhua carbons txais C1 thiab C2.
Yuav ua li cas hauv qab no muab tib yam osazone?
D-Glucose, D-Manose, D-Fructose muab tib osazone.
