Phenylalanine hydroxylase (PAH) is an enzyme crucial for the metabolic conversion of the amino acid phenylalanine to tyrosine. This biochemical reaction is vital for the body's ability to process and utilize amino acids, and it plays a critical role in the biosynthesis of neurotransmitters. The proper function of PAH is essential for maintaining metabolic balance and preventing the accumulation of phenylalanine in the body.
