Application of L-Tyrosine
Functions:
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 recepttyrosine kinases). Phosphorylation of the hydroxyl group changes the activity of the target protein.
Medical use:
Tyrosine is a precursto neurotransmitters increases plasma neurotransmitter levels (particularly dopamine norepinephrine)but has little if any effect on mood.The effect on mood is more noticeable in humans subjected to stressful conditions
It can be used for thyroid function hyperfunction in the medical field.
It can be used as food additives.
It is an important biochemical reagents and the main raw material of polypeptide hormones, antibiotics, L - dopa drugs.
It is also widely used in agricultural scientific research, but also for beverage and preparation of artificial insects feed additives.
