    Product Description

    D-Xylulose is a ketopentose, a monosaccharide containing five carbon atoms and a ketone functional group.1 It is converted from xylitol in the glucoronate-xylulose pathway. D-Xylulokinase catalyzes the ATP-dependent phosphorylation of D-xylulose to produce xylulose 5-phosphate, which is linked to the pentose-phosphate pathway.2

    WARNING This product is not for human or veterinary use.
