    Gluten Free Pure L Tyrosine Powder Promotes Healthy Glandular Function 


        Tyrosine kinases, also known as tyrosine protein kinases, are enzymes that catalyze the phosphorylation of tyrosine residues (sites) in peptide chains. They play an important role in biological metabolism and cell information transmission. Their molecular weight is 56000 and they are enzymes that bind to the inner membrane of cells. The enzyme consists of two domains, one is catalytic domain, which accounts for the majority of the enzyme molecules, including C-terminal and two tyrosine phosphorylation sites; the other is regulatory domain (SH2 domain), including N-terminal, serine phosphorylation site and homologous region of myristoylation.

        The tyrosine phosphorylation sites in the catalytic domain have a great relationship with the expression of tyrosine kinase activity. If these tyrosine sites are phosphorylated, the kinase activity will be inhibited; on the contrary, if these phosphorylated tyrosine sites are treated with phosphatase to dephosphorylate, then the enzyme activity can be significantly increased. The tyrosine phosphorylation sites are close to the C-terminus, but the tyrosine kinases expressed by different genes (such as the products of c-Src gene family) are in different positions. If they are deleted, the kinases will be activated. In addition, the binding site of T antigen and tyrosine kinase expressed in c-Src gene is near to the site 527, which is too close to this site, forming a steric hindrance and hindering the phosphorylation of this site, so it increases the activity of kinase.

        In addition to the homologous region, other parts of SH2 domain are quite different in structure, so it can play a role in regulating kinase activity with different regulatory factors.

    Applications of Tyrosine powder:



    Mental performance - research shows that taking tyrosine improves mental performance under stressful conditions These include cold-induced stress or noise-induced stress.
    Memory - research shows that taking tyrosine improves memory during stressful conditions. These include cold-induced stress or multi-tasking. Tyrosine does not seem to improve memory during less stressful situations.
    Helps support healthy and normal mind performance.
    Phenylketonuria (PKU) - people with PKU are not able to process the amino acid phenylalanine. This amino acid is used by the body to make tyrosine. Because of this, people with PKU can have low levels of tyrosine in the body. To prevent tyrosine levels from becoming too low, people with PKU are advised to consume medical foods containing tyrosine.
    Helps to maintain normal mental alertness, brain activity, mood and blood pressure.
    May decrease stress symptoms, including low mood and performance impairment and improve cognitive performance when under stress.
