The molecule is a monoalkyl phosphate that is pentane substituted at positions 3 and 4 by oxo groups, at position 2 by a hydroxy group and at position 1 by a phosphooxy group (the S-enantiomer). It is a monoalkyl phosphate, an alpha-diketone, a secondary alcohol and a secondary alpha-hydroxy ketone. It is a conjugate acid of a (2S)-2-hydroxy-3,4-diketopentyl phosphate(2-).
