metabolomer
Metabolomer is a term used in chemistry and metabolomics to describe an isomeric form of a metabolite produced during metabolism. The word combines metabolism and isomer, indicating structural variants that share the same molecular formula but differ in connectivity or stereochemistry as a result of enzymatic or chemical transformations in biological systems.
Metabolomers can be configurational isomers (such as enantiomers and diastereomers) or constitutional and tautomeric isomers arising
Characterization typically relies on high-resolution mass spectrometry and nuclear magnetic resonance, often coupled with chromatographic separation
Illustrative examples include epimers of a sugar-derived metabolite that differ at a single stereocenter, or keto–enol
