Sucrose

Vedclass · Answer

(D) hemiacetal group is formed when an alcohol reacts with an aldehyde. In disaccharides,if the anomeric carbon of one monosaccharide unit is involved in a glycosidic linkage,it loses its hemiacetal nature. $1$. Glucose is a monosaccharide and exists in equilibrium with its cyclic hemiacetal form. $2$. Lactose and Maltose are reducing sugars because they contain one free anomeric carbon that retains the hemiacetal group. $3$. Sucrose is a non-reducing sugar because the glycosidic linkage is formed between the anomeric carbons of both glucose and fructose units,thereby eliminating the hemiacetal group in both.
