Glycolaldehyde is the organic compound with the formula HOCH2−CHO. It is the smallest possible molecule that contains both an aldehyde group (−CH=O) and a hydroxyl group (−OH). It is a highly reactive molecule that occurs both in the biosphere and in the interstellar medium. It is normally supplied as a white solid. Although it conforms to the general formula for carbohydrates, Cn(H2O)n, it is not generally considered to be a saccharide.[1]
