Chemical Properties

Valine(2-amino-3-methylbutyric acid) is one of the 20 amino acids that make up proteins. It is an essential 8 amino acids and glucogenic amino acids for the human body. And Valine works with isoleucine and leucine to promote normal body growth, repair tissues, regulate blood sugar, and provide the required energy.

Physical properties

Valine, White crystal or crystalline powder; odorless, slightly sweet and then bitter. Soluble in water, almost insoluble in ethanol.

Definition

ChEBI: L-valine is the L-enantiomer of valine. It has a role as a nutraceutical, a micronutrient, a human metabolite, an algal metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite. It is a pyruvate family amino acid, a proteinogenic amino acid, a valine and a L-alpha-amino acid. It is a conjugate base of a L-valinium. It is a conjugate acid of a L-valinate. It is an enantiomer of a D-valine. It is a tautomer of a L-valine zwitterion.

Synthesis

Valine can be synthesized by hydrolysis of aminoisobutyronitrile which is obtained by amination and cyanation of aminoisoaldehyde. Valine can also be isolated from fish proteins.
