Common Name2-oxobutanoic acid
Description2-oxobutanoic acid is a keto acid and an important intermediate in various metabolic pathways. Its chemical structure features a four-carbon backbone with a ketone functional group at the second carbon, making it a key player in the metabolism of amino acids and carbohydrates. In biological systems, 2-oxobutanoic acid is involved in the transamination reactions, contributing to the synthesis and degradation of amino acids. It is also linked to the citrate cycle, where it plays a role in energy production and metabolic regulation. For instance, studies have shown that 3-methyl-2-oxobutanoic acid, a related compound, was identified in cerebrospinal fluid samples from patients with TBEV infection, highlighting its involvement in metabolic pathways that differentiate disease states (PMID:39569456 ). Additionally, it has been noted that 4,4,4-trifluoro-2-oxobutanoic acid serves as a significant metabolite in the bacterial degradation of fipronil, indicating its relevance in environmental biochemistry (PMID:39549993 ). Furthermore, kinetic studies suggest that 4-methylthio-2-oxobutanoic acid is involved in enzymatic mechanisms that include acetyl-CoA, emphasizing its biochemical significance (PMID:39322014 ).
