Metabolite Identification
Common Name(2R,3R,4R)-2,3,4,5-Tetrahydroxypentanal
Description(2R,3R,4R)-2,3,4,5-Tetrahydroxypentanal, also known as methoxypectin or pectinic acid, belongs to the class of organic compounds known as pentoses. These are monosaccharides in which the carbohydrate moiety contains five carbon atoms (2R,3R,4R)-2,3,4,5-Tetrahydroxypentanal exists in all living organisms, ranging from bacteria to humans (2R,3R,4R)-2,3,4,5-Tetrahydroxypentanal is found, on average, in the highest concentration within flaxseeds (Linum usitatissimum) (2R,3R,4R)-2,3,4,5-Tetrahydroxypentanal has also been detected, but not quantified in, cocoa beans (Theobroma cacao). This could make (2R,3R,4R)-2,3,4,5-tetrahydroxypentanal a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on (2R,3R,4R)-2,3,4,5-Tetrahydroxypentanal. This compound has been identified in human blood as reported by (PMID: 31557052 ). (2r,3r,4r)-2,3,4,5-tetrahydroxypentanal is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically (2R,3R,4R)-2,3,4,5-Tetrahydroxypentanal 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.
