Question

Sucrose is composed of α−α− D-glucose and β−β− D-fructose. These two monosaccharide units are held together by α,β -glycosidic linkage.

• A. True
• B. False

Answer 1

The correct option is A True

The chemical composition of sucrose is $C_{12}{H}_{22}{O}_{11}$. Sucrose is a disaccharide made up of 50% glucose and 50% fructose. It is composed of α−α− D-glucose and β−β− D-fructose. These units are held together by α,β -glycosidic linkage between e, of the unit and $c_e$ of the fructose unit.
