Inborn errors of carbohydrate metabolism

Inborn errors of metabolism can affect the catabolism and anabolism of carbohydrates, such as in lactose intolerance. Carbohydrates account for a major portion of the human diet. These carbohydrates are composed of three principal monosaccharides: glucose, fructose and galactose; in addition, glycogen is the storage form of carbohydrates in humans. The failure to effectively use these molecules accounts for the majority of the inborn errors of human carbohydrates metabolism.
