Note

L-Xylulose (CAS: 527-50-4), also known as L-threo-2-pentulose, is a ketopentose - a monosaccharide containing five carbon atoms, including a ketone functional group. It has the chemical formula C5H10O5. L-Xylulose accumulates in the urine of pentosuria patients. Since L-xylulose is a reducing sugar like D-glucose, pentosuria patients have been wrongly diagnosed in the past to be diabetic.
