General description

4-Methyl-2-oxovaleric acid, also known as α-ketoisocaproic acid (KIC), is a metabolite of leucine. It is commonly used as a building block in the synthesis of leucine and its derivatives, and it plays a role in amination reactions and asymmetric synthesis. Additionally, KIC serves as an intermediate in the formation of Strecker aldehydes.

Application

  • Role in Human Brain Ketometabolism: 4-Methyl-2-oxovaleric acid has been implicated in the temporal patterns of ketometabolism in cerebral microdialysis fluids of patients with traumatic brain injury, underscoring its significance in biochemical pathways within the brain (Eiden et al., 2019).
