Web(B) Glucose and fructose are not anomers. an anomer is a special type of epimer. It is one of two stereoisomers of a cyclic saccharide that differs only in its configuration at the hemiacetal/acetal carbon, also called the anomeric carbon.

D-glucose and D-mannose give the same osazone of the two monosaccharides. Through osazone formation, aldoses are conversed into ketoses. The osazone formation is used in a multitude of syntheses, in the carbohydrate field, as, for example, in the synthesis of L …
