Theanine is the characteristic amino acid in tea. It is synthesized by glutamic acid and ethylamine under the action of theanine synthetase in the root of tea tree. It is an important substance to form tea taste, which is mainly manifested as fresh and sweet. 26 amino acids (6 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.
Tea tree amino acids refers to all 26 amino acids contained in tea, of which 20 are protein-related amino acids, called protein amino acids; There are also six amino acids that are not involved in protein synthesis, which we call non-protein amino acids. Tea is more important in these 6 kinds, the most important of these 6 kinds is theanine, so theanine is one of the amino acids, is also considered to be the characteristic amino acid of tea.
