Common NameD-Ribose 5-phosphate
DescriptionD-Ribose 5-phosphate (CAS: 4300-28-1), Also known as R-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. D-Ribose 5-phosphate exists in all living species, ranging from bacteria to humans. Within humans, D-ribose 5-phosphate participates in a number of enzymatic reactions. In particular, D-ribose 5-phosphate can be biosynthesized from D-ribulose 5-phosphate; which is mediated by the enzyme ribose-5-phosphate isomerase. In addition, D-ribose 5-phosphate can be biosynthesized from D-ribose; which is catalyzed by the enzyme ribokinase. Outside of the human body, D-ribose 5-phosphate has been detected, but not quantified in cow milk and rices. D-Ribose 5-phosphate is both a product and an intermediate of the pentose phosphate pathway. The last step of the oxidative reactions in the pentose phosphate pathway is the production of ribulose 5-phosphate. D-Ribose 5-phosphate is an important intermediate metabolite in the pentose phosphate pathway and in the purine metabolism pathway. The intracellular ribose 5-phosphate concentration is an important determinant of the rate of de novo purine synthesis (PMID: 6699001 ).
