Theanine / ˈ θ iː ən iː n /, also known as L-theanine, L-gamma-glutamylethylamide, or N 5-ethyl-L-glutamine, is a non-proteinogenic amino acid similar to L-glutamate and L-glutamine. It is produced by certain plants such as Camellia sinensis (the tea plant), and by some fungi .
Thiamine is one of the B vitamins and is also known as vitamin B 1. [1] [11] [12] It is a cation that is usually supplied as a chloride salt. [3]It is soluble in water, methanol and glycerol, but practically insoluble in less polar organic solvents.
In enzymology, a theanine hydrolase (EC 3.5.1.65) is an enzyme that catalyzes the chemical reaction N 5 -ethyl-L-glutamine + H 2 O ⇌ {\displaystyle \rightleftharpoons } L-glutamate + ethylamine Thus, the two substrates of this enzyme are N 5 -ethyl-L-glutamine and H 2 O , whereas its two products are L-glutamate and ethylamine .
Thiamine pyrophosphate is a cofactor that is present in all living systems, in which it catalyzes several biochemical reactions. Thiamine pyrophosphate is synthesized in the cytosol and is required in the cytosol for the activity of transketolase and in the mitochondria for the activity of pyruvate-, oxoglutarate- and branched chain keto acid ...
H 2 O + thiamine <=> 4-amino-5-hydroxymethyl-2-methylpyrimidine + 5-(2-hydroxyethyl)-4-methylthiazole + H + [5] Produced by a wide range of plants and bacteria. In these organisms, it is mainly responsible for salvage of thiamine pyrimidine from degradation products, rather than the breakdown of thiamine. [5] In bacteria, it stays inside their ...
