DL-Valine Usage And Synthesis

Chemical Properties	White crystalline powder
Chemical Properties	dl-Valine is odorless.
Occurrence	Reported found in many fruits, plants and animal tissues; in milk and dairy products.
Preparation	By the action of ammonia on α-bromoisovaleric acid; also through a hydantoin intermediate.
Definition	ChEBI: A branched-chain amino acid that consists of glycine in which one of the hydrogens attached to the alpha-carbon is substituted by an isopropyl group.
