C7H14N2O3 (174.1004374)


L-Theanine, also known as L-gamma-glutamylethylamide or N-gamma-ethyl-L-glutamine, is a member of the class of compounds known as glutamine and derivatives. These compounds contain glutamine or a derivative thereof resulting from a reaction of glutamine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. L-Theanine is slightly soluble (in water) and a moderately acidic compound (based on its pKa). L-Theanine can be found in saliva. The regulatory status of theanine varies by country. In Japan, L-theanine has been approved for use in all foods, including herb teas, soft drinks, and desserts. Restrictions apply to infant foods. In the United States, the Food and Drug Administration (FDA) considers it to be generally recognized as safe (GRAS) and allows its sale as a dietary supplement. The German Federal Institute for Risk Assessment, an agency of their Federal Ministry of Food and Agriculture, objects to the addition of L-theanine to beverages. The European Food Safety Authority EFSA advised negatively on health claims related to L-theanine and cognitive function, alleviation of psychological stress, maintenance of normal sleep, and reduction of menstrual discomfort. Therefore, health claims for L-theanine are prohibited in the European Union (Wikipedia). L-Theanine is found in mushrooms and is a constituent of tea (Thea sinensis) and of the fungus Imleria badia. L-Theanine has been shown to exhibit neuroprotectant and neuroprotective functions (PMID: 20416364, 20416364). N(5)-ethyl-L-glutamine is a N(5)-alkylglutamine where the alkyl group is ethyl. It has been isolated from green tea. It has a role as a neuroprotective agent, a plant metabolite and a geroprotector. It is a tautomer of a N(5)-ethyl-L-glutamine zwitterion. Theanine, a precursor of ethylamine, is found in green tea. It is under investigation in clinical trial NCT00291070 (Effects of L-Theanine in Boys With ADHD). See also: Green tea leaf (part of).

KEIO_ID E005 L-Theanine (L-Glutamic Acid γ-ethyl amide) is a non-protein amino acid contained in green tea leaves, which blocks the binding of L-glutamic acid to glutamate receptors in the brain, and with neuroprotective, anticancer and anti-oxidative activities. L-Theanine can pass through the blood–brain barrier and is orally active[1][2][3].

N2-Acetylornithine, also known as N(alpha)-acetylornithine, belongs to the class of organic compounds known as N-acyl-L-alpha-amino acids. These are N-acylated alpha-amino acids which have the L-configuration of the alpha-carbon atom. N-Acetylornithine is a minor component of the deproteinized blood plasma of human blood. Human blood plasma contains a variable amount of acetylornithine, averaging 1.1 +/- 0.4 umol/L (range 0.8-0.2 umol/L). Urine contains a very small amount of acetylornithine, approximately 1 nmol/mg creatinine (1 umol/day) (PMID:508804). Acquisition and generation of the data is financially supported in part by CREST/JST.
