Cov piam thaj tsis txo qis tsis muaj OH pawg txuas nrog cov pa roj carbon monoxide yog li lawv tsis tuaj yeem txo lwm cov tebchaw. Tag nrho cov monosaccharides xws li qabzib yog txo cov suab thaj. Ib qho disaccharide tuaj yeem ua rau txo cov suab thaj lossis tsis txo cov suab thaj. M altose thiab lactose txo cov suab thaj, thaum sucrose yog cov piam thaj tsis txo qis
YPuas sucrose lossis lactose txo qis qab zib?
Yog. M altose (glucose + qabzib) thiab lactose (galactose + qabzib) muaj pab pawg aldehyde dawb thiab yog li txo cov suab thaj. Puas yog sucrose txo cov piam thaj? Tsis yog.
YPuas lactose txo qab zib?
Rau tib yam vim li cas lactose yog txo qab zib. Cov dawb aldehyde tsim los ntawm lub nplhaib qhib tuaj yeem hnov mob nrog Benedict cov tshuaj. Yog li, cov tshuaj lactose muaj ob qho tib si α thiab β anomer ntawm "txo qhov kawg" ntawm cov disaccharide.
Vim li cas sucrose tsis txo qab zib?
Sucrose yog disaccharide carbohydrate. … Raws li peb tuaj yeem pom tau tias cov piam thaj thiab fructose koom nrog hauv glycosidic bonds thiab yog li sucrose tsis tuaj yeem koom nrog cov tshuaj tiv thaiv kom txo tau. Li no, sucrose yog ib qho tsis txo cov suab thaj vim tsis muaj aldehyde dawb lossis ketone nyob ib sab ntawm $\rangle CHOH$ pawg
Cov suab thaj twg thiaj txo tau?
Cov khoom noj khoom haus monosaccharides galactose, qabzib thiab fructoseyog txhua yam txo cov suab thaj.

Dab tsi yog siv cov suab thaj los ua suab thaj?
Qab zib cane yog suav nrog stalks, nplooj thiab hauv paus system. Tus stalk muaj cov kua txiv hmab txiv ntoo siv los ua suab thaj thiab tawg ua ntu hu ua pob qij txha. Txhua qhov sib koom ua ke muaj qhov node (band) thiab ib qho internode (chaw nruab nrab ntawm cov nodes) .
Puas yog dextran txo cov suab thaj?
Tam sim ntawd tom qab kev soj ntsuam ntawm cov enzyme- substrate sib tov tau ua rau ib lossis ntau qhov ntawm cov tshuaj tiv thaiv ( free txo qab zib, dextran, sucrose) . Puas yog dextran A qab zib? Dextran yog polysaccharide uas muaj cov piam thaj monomers txuas feem ntau los ntawm α(1–6) daim ntawv cog lus, tsim los ntawm ntau cov kab mob.
Vim li cas galactose thiaj txo cov suab thaj?
Tag nrho cov monosaccharides txo cov suab thaj vim tias lawv muaj ib pab pawg aldehyde (yog tias lawv yog aldoses aldoses Ib qho aldose yog monosaccharide(ib qho qab zib yooj yim) nrog cov roj carbon qaum saw nrog ib carbonyl pawg ntawm cov pa roj carbon monoxide kawg, ua rau nws yog aldehyde, thiab hydroxyl pawg txuas nrog tag nrho lwm cov pa roj carbon atoms.
Qhov txawv ntawm kev txo qis thiab tsis txo cov suab thaj yog dab tsi?
Txo cov suab thaj yog cov suab thaj uas cov pa roj carbon monoxide muaj OH pawg txuas uas tuaj yeem txo lwm cov tebchaw. Tsis yog- txo cov suab thaj tsis muaj OH pawg txuas nrog cov pa roj carbon monoxide kom lawv tsis tuaj yeem txo lwm cov tebchaw… M altose thiab lactose txo cov suab thaj, thaum sucrose yog cov piam thaj tsis txo qis .
Dab tsi tuaj yeem txo cov suab thaj?
Disaccharides muaj ob lub monosaccharides thiab yuav txo qis lossis tsis txo qis. Txawm tias ib qho kev txo qis disaccharide yuav tsuas muaj qhov txo qhov kawg, vim tias cov disaccharides tau tuav ua ke los ntawm glycosidic bonds, uas muaj tsawg kawg yog ib qho anomeric carbon .
