Biological Activity
Endogenous metabolites is defined as those that are annotated by Kyoto Encyclopedia of Genes and Genomes as substrates or products of the ~1900 metabolic enzymes encoded in our genome. It is clear in the body of literature that there are documented toxic properties for many of these metabolites[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
