Ribulose is a ketopentose — a monosaccharide containing five carbon atoms and including a ketone functional group. It has chemical formula C5H10O5. Two enantiomers are possible D-ribulose (D-erythro-pentulose) and L-ribulose (L-erythro-pentulose). D-Ribulose is the diastereomer of D-xylulose. Ribulose sugars are composed in the pentose phosphate pathway. They are important in the formation of many bioactive substances.
