D-glucose and D-galactose are also epimers due to interchange of configuration of –OH and –H around carbon-4. The interconversion of epimers is known as epimerization. In liver, glucose is epimerized to galactose or vice versa in presence of enzyme UDP-hexose-4-epimerase.Click to see full answer. Correspondingly, what is the stereochemical relationship between D galactose and D glucose?D-glucose and D-galactose can therefore be refered to as epimers as well as diastereomers. The epimer term is useful because in biochemical pathways, compounds with multiple chiral centers are isomerized at one specific center by enzymes known as epimerases.Furthermore, what type of Epimer is D galactose in comparison to D glucose? D-Galactose is an epimer of D-glucose because the two sugars differ only in the configuration at C-4 . D-Mannose is an epimer of D-glucose because the two sugars differ only in the configuration at C-2 . When a molecule such as glucose converts to a cyclic form, it generates a new chiral centre at C-1 . Correspondingly, what is the difference between D glucose and D galactose? They both almost look identical. In the linear form (Fischer Projection), the only difference is: For glucose, the hydroxyl group on the 4th carbon is on the right side of the molecule. For galactose, the hydroxyl group on the 4th carbon is on the left side of the molecule.Are D glucose and D galactose Epimers?The sugars glucose and galactose are epimers. In glucose, the -OH group on the first carbon is in the axial position, the direction opposite the -OH group on carbon C-4. The stereoisomers β-D-glucopyranose and β-D-mannopyranose are epimers because they differ only in the stereochemistry at the C-2 position.
