| Name | D-Xylulose |
|---|
| Description | D-xylulose is a monosaccharide containing five carbon atoms. D-xylulose is converted from xylitol by the enzyme NAD+-linked xylitol dehydrogenase (EC 1.1.1.9) in the glucuronate pathway, the most important xylitol-handling metabolic pathway in mammals. This activity has been described in human erythrocytes. Most likely, D-xylulose (as well as D-arabinose or D-ribulose) is a precursor of the pentiol D-arabitol, since pentitols are derived from their corresponding pentose phosphate precursors via pentoses. This pathway can play a role in inherited metabolic disorders underlying the accumulation of pentitols e.g., ribose 5-phosphate isomerase deficiency and transaldolase deficiency. Although pentitols are present in all living organisms, knowledge concerning their metabolism is limited. (PMID: 15234337, Mol Genet Metabolite 2004 Jul;82(3):231-7.) [HMDB]. D-Xylulose is found in many foods, some of which are garden onion, american cranberry, cucumber, and radish. |
