Amino Acids

4-Iodo-L-phenylalanine may be used in protein engineering as a model unnatural α amino acid to alter primary amino acid composition via the opal (UGA) codon.

Sodium 4-methyl-2-oxovalerate is an inhibitor of pyruvate transport and is used for production of pyrazinones. It is a condensation of this compound with α-amino ketones and subsequent cyclization provides pyrazinones.Condensation with α-amino
