Monosaccharides and Disaccharides

Monosaccharides are the simplest form of carbohydrates, consisting of single sugar molecules such as glucose and fructose, which serve as fundamental energy sources for cells. Disaccharides are carbohydrates formed by the chemical bonding of two monosaccharides, such as sucrose (glucose + fructose) and lactose (glucose + galactose), and are also utilized for energy.
