About L Tyrosine
Freely soluble in formic acid, very slightlysoluble in water,practically insoluble in ethanol and in ether. 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. It 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.
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.
