How does the C4 epimer of D-glucose, D-galactose, differ in chemical properties compared to D-glucose?

D-galactose has different reactivity in enzymatic reactions due to the altered orientation of the hydroxyl group at C4.

D-galactose has a lower melting point due to decreased hydrogen bonding.

D-galactose has a higher solubility in water due to its epimeric structure.

D-galactose is less reactive in glycosidic bond formation due to steric hindrance.
