The "sedative" in tea, the role and characteristics of theanine
Tea contains about 1% to 4% of amino acids, of which 26 have been found and identified, including 20 protein amino acids and 6 non-protein amino acids. Among these 6 non-protein amino acids, the most important is theanine which is almost unique to tea, accounting for 1% to 2% of the dry matter of tea, and it accounts for about 50% of the total. The most important amino acid in tea we discuss is theanine.
Amino acids in tea are not only the basic unit of protein but also an important component of active peptides, enzymes, and other biologically active molecules. The composition and content of amino acids in tea as well as their degradation products and transformation products also directly affect the quality of tea.
Theanine has regulatory functions in the secretion of immune cytokines, neurotransmitters, and hormones. Can significantly improve the body's immunity against virus invasion.
Theanine acts to lower blood pressure by regulating the concentration of neurotransmitters in the brain.
Theanine can promote the release of dopamine in the brain center, improve the physiological activity of dopamine in the brain, make people feel comfortable and happy, help reduce stress and relieve symptoms of fatigue.
Now that theanine is developed as a medicine or health product, one of the most valuable aspects is to improve sleep.
