Part Description

LP15792-2   Phenylalanine
Phenylalanine is an essential alpha-amino acid. It exists in two forms, a D and an L form, which are enantiomers (mirror-image molecules) of each other. It has a benzyl side chain and its name comes from its chemical structures that consists of a phenyl group substituted for one of the hydrogens in the side chain of alanine. Because of its phenyl group, phenylalanine is an aromatic compound that at room temperature exists as a white, powdery solid. L -phenylalanine (LPA) is an electrically-neutral amino acid and its enantiomer, D -phenylalanine (DPA), can be synthesized artificially. L -phenylalanine can also be converted into L -tyrosine, another one of the twenty protein-forming amino acids. Copyright Text is available under the Creative Commons Attribution/Share-Alike License.
