The configuration at the acetal carbon atom as α or β has to be identified. Concept introduction: In a cyclic monosaccharide, the replacement of an − OH group of the hemiacetal carbon by an − OR group results in the formation of an acetal. The acetal formed is known as a glycoside. If both the − CH 2 OH group and − OR group points in the same direction, then the configuration is β . If both the − CH 2 OH group and − OR group points in different direction, then the configuration is α .
