IAspartic acid is a ubiquitous acidic amino acid.
The content of tea leaves is relatively constant. White monoclinic columnar crystal, slightly soluble in water, with sour taste, melting point 278ºC. The content in the young buds and leaves is 0.05% ~ 0.25%, and the content of Gaoshan tea can reach 0.4% ~ 0.5%. The contents decreased gradually with the aging of leaves, but in the annual growth period, the contents were more in any season, and the important role in the amino acid library was the same as that of glutamic acid. The regional difference of tea quality is related to the fluctuation of this acid. L-aspartic acid is a coding amino acid in protein synthesis, a non-essential amino acid and a glycogenic amino acid in mammals, and can be a neurotransmitter.
Used as food additive, flavoring agent for drinks, ice cream, etc. It can be used as medicine, liver function promoter, fatigue recovery agent, amino acid infusion agent, etc. It can be used alone or in combination with other drugs; Used as biochemical reagents and media; Also used as intermediates in organic synthesis; Synthetic aspartame; Cosmetic additives, etc.
