Metabolite Identification
Common NameDPG
DescriptionDPG is a metabolite described in biomedical literature, specifically as 2,3-diphosphoglycerate (2,3-DPG), which belongs to the class of phosphoglycerates. This compound plays a critical role in red blood cell (RBC) physiology, particularly in modulating hemoglobin's affinity for oxygen. Measurements of metabolites such as 2,3-DPG have been relied upon as proxies for in vivo function, although their predictive value for clinical efficacy is not well substantiated (PMID:40987756 ). Following the discontinuation of the only validated commercial assay for 2,3-DPG, a review of existing literature and a retrospective analysis of datasets from two blood centers in North America were conducted to evaluate alternatives like adenosine-5'-triphosphate (ATP) and p50 (PMID:40987756 ). The literature did not provide sufficient evidence to support adopting p50 in place of 2,3-DPG (PMID:40987756 ). Although the assays are complementary, several exceptions were noted where biological and technical factors reduced the correlation strength between 2,3-DPG and p50 (PMID:40987756 ). Additionally, ATP was not well correlated with 2,3-DPG or p50 in quality monitoring datasets (PMID:40987756 ). Overall, there is limited literature on the metabolite's comprehensive characterization and its implications in RBC quality assessment.
