Detailed explanation-1: -Galactose is an isomer of glucose. This means that they both share the same formula: C6H12O6. The only real difference is that the-H and-OH groups on carbon 4 (labelled) face in different directions.

Detailed explanation-2: -Glucose, fructose and galactose are known as isomers because they have the same chemical formula and they basically vary only in the arrangement of atoms in the molecule.

Detailed explanation-3: -Diastereomers are optical isomers of each other with not being mirror images of each other. Since the same can be seen in case of glucose and galactose, hence they are diastereomers.-Therefore, glucose and galactose are diastereomers.

Detailed explanation-4: -Glucose and Fructose are Which Isomers Glucose and fructose are functional isomers of each other because they have same molecular formula that is C6H12O6 But different functional group in their chemical formula.

Detailed explanation-5: -That single different makes D-glucose and D-galactose epimers. They are not enantiomers, or diastereomers, or isomers, they are only epimers.
