The bond in α-D-glucose must be broken to change its configuration to β-D-glucose. Introduction : Diastereomers are those stereoisomers who differ in orientation of two chiral centers due to which the isomers are not the mirror images of each other. The cyclic forms of diastereoisomeric sugars which differ at the anomeric carbon (carbonyl carbon which reacts to form hemiacetal) are known as anomers. Hemiacetal is formed when the carbonyl carbon (partially positive) and oxygen of hydroxyl group (partially negative) forms a bond. The hemiacetal anomers exist in alpha and beta forms based on the site of substituent at anomeric carbon.
