Is a ketopentose xylulose, which is a monosaccharide having five carbon atoms (hence pentose ), and a keto group at the C2 atom (hence ketosis ).

The molecule comes in the form of xylulose -5- phosphates ago as an intermediate in the pentose phosphate pathway and as a signaling molecule.

Xylulose gives a positive Fehling's test. They can be prepared by reaction of xylose with pyridine in the heat. Xylulose forms an osazone, which melts at 160-163 ° C. The L-form can be detected in the urine Pentosuria. Biosynthesis probably proceeds from D - glucuronic acid.
