Metabolite Identification
Common Name2-oxooctanoic acid
Description2-oxooctanoic acid is a member of the α-keto acid chemical class, characterized by its ketone functional group adjacent to a carboxylic acid. This metabolite plays a role in various biochemical pathways, including the conversion of fatty acids, as demonstrated by its production from octanoic acid under mild conditions, achieving over 99% conversion without hydroxyacid accumulation (PMID:29125663 ). Its unique reactivity is highlighted in studies showing that 2-oxooctanoic acid undergoes distinct acid-mediated photochemical processes compared to other compounds, contributing to the formation of amphiphilic molecules (PMID:24559493 ). Additionally, it has been shown to react with other α-keto acids, such as pyruvic acid, in the synthesis of fatty acid derivatives (PMID:29806009 ). The compound also exhibits increased binding affinity in certain enzymatic variants, indicating its significance in metabolic pathways involving α- and β-unnatural amino acids (PMID:30478262 ). Furthermore, the hydration and deprotonation characteristics of 2-oxooctanoic acid have been studied in relation to pH, providing insight into its behavior in aqueous environments (PMID:29032688 ).
