L-Phenyl-d5-alanine Chemical Properties, Uses, Production

Description

L-Phenylalanine-d5 is a stable isotope of phenylalanine can be used to study the metabolic effects and proteins expression by the analytical methods using NMR.

Chemical Properties

White Solid

Uses

Labeled L-Phenylalanine is an essential amino acid. L-Phenylalanine is biologically converted into L-tyrosine, another one of the DNA-encoded amino acids, which in turn is converted to L-DOPA and further converted into dopamine, norepinephrine, and epinephrine. L-Phenylalanine is produced for medical, feed, and nutritional applications such as in the preparation of Aspartame.

Definition

ChEBI: A deuterated compound that is phenylalanine in which the five aromatic hydrogens are replaced by deuterium.

IC 50

NMDA Receptor
