Common Name

Xylulose 5-phosphate

Description

Xylulose 5-phosphate, also known as xylulose-p or xu-5-p, belongs to the class of organic compounds known as pentose phosphates. These are carbohydrate derivatives containing a pentose substituted by one or more phosphate groups. Xylulose 5-phosphate is an extremely weak basic (essentially neutral) compound (based on its pKa). Xylulose 5-phosphate exists in all living species, ranging from bacteria to humans. Within humans, xylulose 5-phosphate participates in a number of enzymatic reactions. In particular, xylulose 5-phosphate can be biosynthesized from D-ribulose 5-phosphate; which is catalyzed by the enzyme ribulose-phosphate 3-epimerase. In addition, D-ribose 5-phosphate and xylulose 5-phosphate can be biosynthesized from D-glyceraldehyde 3-phosphate and D-sedoheptulose 7-phosphate through the action of the enzyme transketolase. In humans, xylulose 5-phosphate is involved in pentose phosphate pathway. Outside of the human body, Xylulose 5-phosphate has been detected, but not quantified in, several different foods, such as parsnips, cabbages, common beets, celery stalks, and ostrich ferns. This could make xylulose 5-phosphate a potential biomarker for the consumption of these foods. The D-enantiomer of xylulose 5-phosphate. Xylulose 5-phosphate is expected to be in Cannabis as all living plants are known to produce and metabolize it.
