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.

Formaldehyde is an important organic raw material, which is mainly used in plastic industry (such as phenolic resin, urea formaldehyde plastic electric jade), synthetic fiber (such as synthetic vinylon polyvinyl formal), leather industry, medicine, dyes, etc. Formalin has the ability of sterilization and antisepsis. It can soak biological samples. Its dilute solution (0.1-0.5%) can be used to soak seeds and disinfect seeds in agriculture. Catalytic oxidation is commonly used in industry to produce formaldehyde from methanol. Formaldehyde can react with silver ammonia solution to produce silver mirror, so that a thin layer of metallic silver as bright as a mirror is attached to the inner wall of the test tube (combined silver is reduced and formaldehyde is oxidized); It reacts with the newly prepared copper hydroxide suspension to form red precipitated cuprous oxide.

Aspartic Acid is a non-essential amino acid in humans, Aspartic Acid has an overall negative charge and plays an important role in the synthesis of other amino acids and in the citric acid and urea cycles. Asparagine, arginine, lysine, methionine, isoleucine, and some nucleotides are synthesized from aspartic acid. Aspartic acid also serves as a neurotransmitter.

L-cystine is a nutritional supplement. It is used for breast milk of milk powder. It is a non essential amino acid. It is essential for skin and hair, and can promote the treatment of surgery and trauma. Stimulate hematopoiesis and promote leucopoiesis. It can promote the oxidation and reduction of body cells. It can also be used as an additive for cosmetics. It can promote wound healing, prevent skin allergy and treat eczema.

This product is a cationic surfactant. It can be used as bactericide, gargle, disinfectant and intestinal absorption inhibitor. It can also be used as a micelle solubilizing spectrophotometric reagent.
