Metabolite Identification
Common NameRibose-5-phosphate
DescriptionRibose-5-phosphate 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. In humans, ribose-5-phosphate is involved in the metabolic disorder called the transaldolase deficiency pathway. Ribose-5-phosphate is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review a significant number of articles have been published on Ribose-5-phosphate. This compound has been identified in human blood as reported by (PMID: 31557052 ). Ribose-5-phosphate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Ribose-5-phosphate is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.

Enzymes

General function:
Not Available
Specific function:
Catalyzes the reversible transfer of a two-carbon ketol group from sedoheptulose-7-phosphate to glyceraldehyde-3-phosphate, producing xylulose-5-phosphate and ribose-5-phosphate. Catalyzes the transfer of a two-carbon ketol group from a ketose donor to an aldose acceptor, via a covalent intermediate with the cofactor thiamine pyrophosphate.
