Products Description:

Tyrosine (abbreviated as Tyr or Y)or 4-hydroxyphenylalanine, is one of the 22 amino acids that are used by cells to synthesize proteins. Its codonsare UAC and UAU. It is a non-essential amino acid with a polar side group. The word "tyrosine" is from the Greek tyros, meaning cheese, as it wasfirst discovered in 1846 by German chemist Justus von Liebig in the proteincasein from cheese. It is called tyrosyl when referred to as a functional groupor side chain.yrosine is a precursor to neurotransmitters and increases plasmaneurotransmitter levels (particularly DOPAM and norepinephrine) but haslittle if any effect on mood. The effect on mood is more noticeable in humans subjected to stressful conditions.
Aside from being a proteinogenic aminoacid, tyrosine has a special role by virtue of the phenol functionality. Itoccurs in proteins that are part of signal transduction processes. It functionsas a receiver of phosphate groups that are transferred by way of proteinkinases (so-called receptor tyrosine kinases). Phosphorylation of the hydroxylgroup changes the activity of the target protein.
A tyrosine residue also plays an important role in photosynthesis. In chloroplasts (photosystem II), it acts as anelectron donor in the reduction of oxidized chlorophyll. In this process, it undergoes deprotonation of its phenolic OH-group. This radical is subsequentlyreduced in the photosystem II by the four core manganese clusters.
