GENERAL DESCRIPTION & APPLICATIONS

Phenylalanine is an essential amino acid obtained in the levo form by hydrolysis of proteins (as lactalbumin). Branched amino-acids (Valine, Isoleucine and Leucine ) with tryptophan and phenylalanine (aromatic side chain amino acids) contribute to the structure of protein by the tendency of its side chain composed only of carbon and hydrogen to participate in hydrophobic interactions which determines the tertiary structure of the peptide chain. In addition to its role in protein synthesis, it is the metabolic precursor of the non-essential amino acid tyrosine which makes hormones, such as norepinephrine and epinephrine in the normal body. The prefix nor- describes normal structure which has no branched chain of carbon atoms. But in case of norepinephrine, it has one less methylene group than its homologue, epinephrine. Phenylalanine is also converted to phenylethylamine occuring naturally in the brain to elevate mood. It is used to treat depression, inflammation, chronic pain, Parkinson's disease. Phenylalanine is a key intermediate to make aspartame. N-alpha-t-BOC-D-phenylalanine is used in biological research of peptidomimetics. It is used to prepare unnatural and unusual amino acids and amino acid analogs as well as to modify peptides.
