Term Description

This test measures the phenylalanine (PHE) level in children who have been diagnosed with phenylketonuria or tyrosinemia and are on a therapeutic diet for their condition. The parent of the patient collects the dried blood spot specimen at home and sends it to the laboratory. The phenylalanine level is used in combination with tyrosine and succinylacetone levels to monitor the patient's progress.

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.
