D -Glucose shows mutarotation because,

Statement-1: Glucose is in pyranose form and has free anomeric hydroxyl group Statement-1: In sucrose, glucose is in pyranose form and fructose is in furanose form.

(A) Sucrose is not a reducing sugar. (R) In sucrose, glucose is in pyranose form and fructose is in furanose form.

(A) In a sucrose molecule, glucose is present in the furanose form and fructose is present in the pyranose form. (R) Pyranose and furanose are homocyclic ring compounds.

Mutarotation is the change in specific rotation of an optically active compound in solution with time to an equilibrium value. Interconversion is possible only if sugar has anomeric hydroxyl group i.e., sugar is reducing. Diastereomers which differ in configuration of chiral carbon developed in hemiacetal formation are called anomers. Epimers are a pair of stereoisomers which differ in the configuration about one of its chiral carbon alpha- glucose and beta- glucose differ in configuration at ______ and are called
