Is monosaccharide better or disaccharide better? What are their advantages and disadvantages?

Monosaccharide includes glucose, fructose, ribose, deoxyribose and galactose. Glucose is the main energy substance needed by cell life activities, which cannot be hydrolyzed and can be directly absorbed by cells. Ribose and deoxyribose are part of nucleic acid, which is genetic material, so it is also very important. Disaccharides include sucrose, maltose and lactose, and disaccharides can be hydrolyzed into monosaccharides. Although they exist in different forms, they are all very important for the survival of living things.
