Theanine is a characteristic amino acid in tea. It is synthesized in the roots of tea plants under the action of theanine synthase from glutamic acid and ethylamine. It is an important substance that forms the taste of tea. It is mainly expressed as fresh and sweet. It is tea. The main ingredient of Shengjin Runtian. Twenty-six amino acids (6 non-protein amino acids) are identified in tea, which generally account for 1% to 5% of the dry weight of tea, and theanine accounts for more than 50% of the total free amino acids of tea.
Tea tree amino acids refer to all 26 amino acids contained in tea, 20 of which are protein-related amino acids, called protein amino acids; there are 6 amino acids that have nothing to do with protein synthesis, we call non-protein amino acids. The more important ones in tea are these 6 types. The most important of these 6 types is theanine, so theanine is one of the amino acids and is also considered to be the characteristic amino acid of tea.
As the characteristic non-protein amino acid with the highest content in tea, theanine is safe and non-toxic and has a variety of biological activities such as antioxidant, immune regulation, anti-aging, and antagonistic cell excitotoxicity caused by excessive glutamate. At the same time, as an alkyl amine, L-theanine can activate γ-T immune cells to promote cell proliferation and cytokine secretion, enhance the ability to resist tumor cells and reduce external microbial infections, and reduce the risk of colds and flu. .
1. Seasoning. Mainly used for green tea, the amount is not specified. Nutritional supplements.
2. The amount of seasoning (fragrance component of green tea) is not specified.
3. Used as a food additive.
4. The sedative effect when added to food, the flavor improvement effect of L-theanine, enhances immunity, lowers blood pressure, improves the brain, promotes the brain's learning and memory functions, and effectively enhances the liver's detoxification function. Pressure effect.
5. The analog of glutamine is also one of the ingredients of green tea. It can bind to AMPA, magnesia and NMDA glycine receptors of rat cortical neurons but has lower affinity than glutamate. It has been studied as a glutamate transport inhibitor to prevent the uptake of glutamate by cells of mice bearing M5076 ovarian sarcoma and increase the effect of doxorubicin on tumor growth in M5076 mice.
