Ib daim ntawv cog lus glycosidic tsim los ntawm cov tshuaj tiv thaiv condensation, uas txhais tau hais tias ib qho dej molecule yog tsim thaum lub sij hawm tsim glycoside. … Ua ke lawv ua H2O, lossis dej. Qhov tshwm sim ntawm glycosidic daim ntawv cog lus yog cov piam thaj molecule txuas mus rau lwm lub molecule ntawm ib pawg ether.
Glycosidic bonds tsim li cas?
Ib daim ntawv cog lus glycosidic yog tsim nruab nrab ntawm pawg hemiacetal lossis hemiketal pawg ntawm saccharide (los yog cov molecule tau los ntawm saccharide) thiab pawg hydroxyl ntawm qee qhov sib xyaw xws li cawv. Ib yam khoom uas muaj glycosidic daim ntawv cog lus yog glycoside.
txhais li cas los ntawm glycosidic linkage?
Ib daim ntawv cog lus glycosidic lossis glycosidic linkage yog hom covalent daim ntawv cog lus uas koom nrog cov carbohydrates (qab zib) molecule rau lwm pab pawg, uas tej zaum yuav lossis tsis yog lwm cov carbohydrate.
Dab tsi yog glycosidic linkage piav qhia nws tsim thiab vim li cas?
Qhia txog kev tsim cov glycosidic linkage. Cov ntawv cog lus uas tsim los ntawm ob lub monosaccharides thaum cov carbohydrates loj (disaccharides thiab polysaccharides) tau ua ke Nws koom nrog cov tshuaj tiv thaiv ntawm ob pawg -C-OH, tsim dej, thiab -C-O-C- daim ntawv cog lus. Qhov no -C-O-C- daim ntawv cog lus hu ua glycosidic txuas.
Puas glycosidic linkages tsim los ntawm lub cev qhuav dej?
Glycosidic linkages yog hydrolyzed, los yog tawg, los ntawm kev sib ntxiv ntawm cov dej molecule thiab cov catalyst. Carbohydrates sib txuas nrog ib leeg los ntawm kev sib txuas glycosidic. Cov ntawv cog lus no tsim los ntawm cov tshuaj tiv thaiv lub cev qhuav dej, tseem hu ua cov tshuaj tiv thaiv condensation lossis lub cev qhuav dej.
