N-acetyl-L-tyrosine is an N-acetyltyrosine in which the chiral centre has L configuration. It has a role as an EC 2.1.1.4 (acetylserotonin O-methyltransferase) inhibitor, a biomarker and a human urinary metabolite. It is a N-acyl-L-tyrosine and a N-acetyltyrosine. It is a conjugate acid of a N-acetyl-L-tyrosinate.
N-acetyltyrosine, also referred to as N-acetyl-L-tyrosine, is used in place of as a tyrosine precursor. Tyrosine is a non-essential amino acid with a polar side group. N-acetyltyrosine is administered as parenteral nutrition or intravenous infusion due to its enhanced solubility compared to tyrosine 2. It is typically administered as a source of nutritional support where oral nutrition is inadequate or cannot be tolerated.
