carbon‚ hydrogen‚ and oxygen with a 2:1 ratio between carbon and oxygen. A carbohydrate‚ or saccharide‚ is a group including sugars and starches (Volesky). The monomer of a carbohydrate is a monosaccharide. Monosaccharides can bond with others in a dehydration synthesis. This is a special reaction that consists of the removal of a water molecule to combine two or more monosaccharides (Volesky). Two bonded monosaccharides is a disaccharide.
