Norvaline is a non-proteinogenic branched-chain amino acid. It has previously been reported to be a natural component of an antifungal peptide of Bacillus subtilis. Norvaline and other modified branched chain amino acids have received attention in recent studies as they appear to be incorporated in some recombinant proteins found in E. coli.

It is used therapeutically to stimulate gastric and pancreatic secretions and in the treatment of hyperlipoproteinemias.
