Explanation:
Detailed explanation-1: -Formation. The formation of a disaccharide molecule from two monosaccharide molecules proceeds by displacing a hydroxy group from one molecule and a hydrogen nucleus (a proton) from the other, so that the now vacant bonds on the monosaccharides join the two monomers together.
Detailed explanation-2: -Hence, the functional groups in open structure of monosaccharide are hydroxyl, and aldehyde or ketone, while in ring structure it is hemiacetal or hemiketal.
