Freely soluble in formic acid, very slightlysoluble in water,practically insoluble in ethanol and in . Dissolve in dilute hydrochloric acid and in dilute nitric acid. Aside from being a proteinogenic amino acid, tyrosine has a special role by virtue of the phenol functionality. It occurs in proteins that are part of signal transduction processes. L-tyrosine functions as a receiver of phosphate groups that are transferred by way of protein kinases (so-called receptor tyrosine kinases). Phosphorylation of the hydroxyl group changes the activity of the target protein.China H&Z® L-tyrosine is a precursor to neurotransmitters and increasesplasma neurotransmitter levels (particularly and )but has little if any effect on mood.The effect on mood is more noticeable in humans subjected to stressful conditions.

L-Tyrosine CAS:60-18-4 Introduction:
H&Z® L-Tyrosine is a precursor to neurotransmitters and increasesplasma neurotransmitter levels (particularly dopamine and norepinephrine)but has little if any effect on mood.The effect on mood is more noticeable in humans subjected to stressful conditions.
L-Tyrosine, it is an essential amino acid, which is a kind of important nutrition for human and animal metabolism, growth and development plays an important role, could be widely used in food, feed, pharmaceutical and chemical industry, etc.
