L-Tyrosine, CAS # 60-18-4, is an aromatic non-essential amino acid that is considered a fundamental metabolite, involved in protein synthesis and photosynthesis.

This Thermo Scientific Chemicals brand product was originally part of the Acros Organics product portfolio. Some documentation and label information may refer to the legacy brand. The original Acros Organics product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

General description

• L-Tyrosine is the levorotatory isomer of the aromatic amino acid tyrosine, synthesized in vivo from L-phenylalanine
• It is available as a crystalline, off-white powder, stable at room temperature, and soluble in hydrochloric acid

Applications

• In vivo L-tyrosine is involved in protein synthesis and is a precursor to alkaloids such as morphine, neurotransmitters, epinephrine, p-coumaric acid, thyroxine, pigment melanin and catecholamines.
• Used as a supplement, L-tyrosine has been shown to increase levels of the neurotransmitters, dopamine, adrenaline, and norepinephrine in the brain
• It is considered an essential dietary supplement for phenylketonuria patients who lack the enzyme phenylalanine hydroxylase, and hence cannot convert phenylalanine into tyrosine
• L-tyrosine plays a vital role as an electron-carrier in the process of photosynthesis
• Due to its role in the synthesis of catecholamines, L-tyrosine is also used in research to study its impact on stress
