Glycolaldehyde (HOCH2-CH=O, IUPAC name 2-hydroxyethanal) is a type of diose (2-carbon monosaccharide). Glycolaldehyde is readily converted to acetyl coenzyme A. It has an aldehyde and a hydroxyl group. However, it is not actually a sugar, because there is only one hydroxyl group. Glycolaldehyde is formed from many sources, including the amino acid glycine and from purone catabolism. It can form by action of ketolase on fructose 1,6-bisphosphate in an alternate glycolysis pathway. This compound is transferred by thiamin pyrophosphate during the pentose phosphate shunt.; Glycolaldehyde is an intermediate in the formose reaction.
