Vedclass · Answer

(A) Lactose is a disaccharide with the formula $C_{12}H_{22}O_{11}$.On hydrolysis in the presence of an acid or the enzyme lactase,it undergoes cleavage to produce one molecule of $D-(+)$-glucose and one molecule of $D-(+)$-galactose.The chemical reaction is:$C_{12}H_{22}O_{11} + H_2O$ $\xrightarrow{H_3O^+ 	ext{ or lactase}} C_6H_{12}O_6 (	ext{Glucose}) + C_6H_{12}O_6 (	ext{Galactose})$Therefore,one mole of lactose yields $1.0 \ mol$ of glucose and $1.0 \ mol$ of galactose.
