Nyob rau hauv trehalose, ob lub qabzib residues koom nrog α-txuas los ntawm ob qho tib si carbon atoms; Yog li ntawd, cov disaccharide tsis yog txo cov suab thaj, lossis nws tsis pom kev hloov pauv.

Cov qab zib twg tsis qhia kev hloov pauv?

Yog li ntawd, sucrose yog qhov tsis muaj peev xwm qhia txog kev hloov pauv. Glucose kuj yog ib qho kev txo qis qab zib qhia mutarotation. Peb tuaj yeem txiav txim siab tias Sucrose tsis yog txo cov suab thaj vim tias nws tsis muaj pawg hydroxyl hauv lub nplhaib. Li no, sucrose tsis qhia mutarotation.

YPuas yog trehalose ib monosaccharide?

Trehalose yog ib qho tsis txaus ntseeg vim nws yog hydrolyzed rau hauv ob lub molecules ntawm glucose (ib monosaccharide).

Puas yog trehalose tsis txo lossis txo cov suab thaj?

Trehalose (α-d-glucopyranosyl α-d-glucopyranoside) yog tsis txo qis disaccharide uas ob d-glucose residues txuas los ntawm txoj haujlwm anomeric rau ib qho. lwm. Trehalose yog dav nyob rau hauv cov kab mob, fungi, poov xab, kab thiab nroj tsuag, tab sis yog tsis tuaj ntawm vertebrates.

Qhov twg hauv qab no yuav qhia txog kev hloov pauv?

Yog tsis muaj cov pab pawg hydroxyl no, lub nplhaib tsis tuaj yeem qhib thiab kaw thiab yog li tsis muaj kev hloov pauv. Glucose, fructose, m altose thiab galactose txhua tus muaj cov pab pawg hydroxyl dawb thiab yog li paub tias txo cov suab thaj. Li no, tag nrho cov no yuav raug hloov pauv.
