Brief Introduction
Theanine is a characteristic amino acid in tea, which is synthesized by glutamic acid and ethylamine under the action of theanine synthetase in the root of tea plant. It is an important substance to form the taste of tea, which is mainly manifested as fresh and sweet, and is the main component of tea. 26 kinds of amino acids (6 kinds of non protein amino acids) were identified in tea, which generally accounted for 1% ~ 5% of the dry weight of tea, and theanine accounted for more than 50% of the total free amino acids in tea. As the most abundant characteristic non protein amino acid in tea, theanine is safe, non-toxic and has many biological activities, such as antioxidation, immune regulation, anti-aging, antagonizing cell excitotoxicity caused by excessive glutamate. At the same time, L-theanine, as an alkyl amine, can be activated γ- T immune cells promote cell proliferation and cytokine secretion, enhance the ability to resist tumor cells, reduce the infection of external microorganisms, and reduce the risk of cold and influenza.

Brief Introduction
L-Cysteine is a kind of nonessential amino acid, which exists in keratin. Keratin is the main protein of nails, toenails, skin and hair. The relationship between L-cysteine and cystine is very close. Two molecules of L-cysteine form one molecule of cystine. L-Cysteine is more unstable. It is easy to become cystine which can also be reduced to L-cysteine. Both of them are sulfur-containing amino acids, which have effects on skin formation and detoxification. L-Cysteine is mainly used in cosmetics, medicine and food. In cosmetics, it is used to prepare perm, sunscreen, hair perfume and hair essence. In the field of medicine, it is used to prepare methyl cysteine, ethyl cysteine, acetylcysteine, methyl cysteine, ethyl cysteine and comprehensive amino acid preparations. L-Cysteine can also be used as a protective drug against radiation injury. In food, L-cysteine is used as bread fermentation auxiliary (ripening agent), antioxidant stabilizer for milk powder and fruit juice, and nutrient for pet animal food.
