- organic compounds composed of carbon, oxygen, and hydrogen; includes the sugars and starches.
- Components of food containing carbon, hydrogen and oxygen. The term carbohydrate encompasses simple sugars, monosaccharides (eg. Glucose) and disaccharides (eg. Sucrose), oligosaccharides (containing several monosaccharide units) and polysaccharides. Starch is the only important food polysaccharide that can be digested in the small intestine. Starch and simple sugars are "available carbohydrates". The indigestible polysaccharides are the main components of "dietary fibre".
