—— Product Detail ——

Product Overview

L-Phenylalanine (CAS 63-91-2) is an essential aromatic amino acid with the molecular formula C₉H₁₁NO₂ and a molecular weight of 165.19 g/mol. It is a white crystalline powder that is sparingly soluble in water. L-Phenylalanine is one of the nine essential amino acids and is a precursor for the biosynthesis of tyrosine, dopamine, norepinephrine, and epinephrine. It is widely used in nutritional supplements, artificial sweetener production (aspartame), and biochemical research.

Synthetic Process

L-Phenylalanine is typically produced by fermentation using microorganisms such as Escherichia coli or Corynebacterium glutamicum, followed by extraction and purification.

Mechanism of Action

L-Phenylalanine is converted to L-tyrosine by phenylalanine hydroxylase, initiating the biosynthesis of catecholamine neurotransmitters and melanin.
