CAS 13921-90-9: (+)-3-Amino-3-phenylpropanoic acid

Description:(+)-3-Amino-3-phenylpropanoic acid, also known as phenylalanine, is an α-amino acid that plays a crucial role in the biosynthesis of proteins. It is characterized by the presence of an amino group (-NH2), a carboxyl group (-COOH), and a phenyl side chain, which contributes to its aromatic properties. This compound is optically active, with the (+) designation indicating that it is the levorotatory enantiomer. It is soluble in water and exhibits a neutral to slightly basic pH in solution. As a building block of proteins, phenylalanine is essential for the synthesis of neurotransmitters such as dopamine, norepinephrine, and epinephrine. It is also a precursor for the synthesis of tyrosine, another important amino acid. In terms of safety, individuals with phenylketonuria (PKU) must monitor their intake of phenylalanine, as they cannot metabolize it properly, leading to potential health issues. Overall, (+)-3-Amino-3-phenylpropanoic acid is significant in both biological and nutritional contexts.
