Product Description

Description of L-Theanine

L-Theanine is a characteristic amino acid in tea, which is synthesized by glutamic acid and ethylamine in the root of tea tree under the action of theanine synthase. Theanine is an important substance to form the taste of tea, which is mainly fresh and sweet, and is the main component of tea Chemicalbook. 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, while theanine accounted for more than 50% of the total free amino acids in tea.
Theanine is an amino acid contained only in tea, which contains the most theanine. L-theanine is synthesized in the root of tea plant, transferred to leaves through branches, and accumulated in leaves. Under Chemicalbook sunlight, L-theanine will be transformed into catechuic acid, so the content of L-theanine is higher in high-grade green tea under shading cultivation, but less in general crude tea, while the content of polyphenols is increased.
