L-Valine

Valine was isolated in 1901 by the chemist Emil Fischer from casein and is acquired by hydrolyzing proteins. Racemic valine can be synthesized by bromination of isovaleric acid followed by amination of the α-bromo derivative.

Load 3D Structure of Valine

L-Valine is a branched-chain essential amino acid that has stimulant activity. Valine helps prevent the breakdown of muscle by supplying the muscles with extra glucose for energy production during intense physical activity. It is a precursor in the penicillin biosynthetic pathway. Valine inhibits the transport of tryptophan across the blood-brain barrier.
