L-Theanine Usage And Synthesis

General Description Theanine is an abundant non-protein derived amino acid that was first isolated from green tea leaves in the late 1940s by Sakato[1]. Theanine has been named as 2-amino-4-[ethylcarbamoyl]butyric acid by the International Union of Pure and Applied Chemistry [IUPAC]. However, it has also been referred to as γ -glutamylethylamide, 5-N-ethylglutamine, γ -glutamyl-L-ethylamide, γ -ethylamino-L-glutamic acid and γ -L-glu-ethylamide.2–5 Similar to other amino acids in nature, theanine is a chiral species and occurs in nature predominantly as the L-[S]enantiomer [Fig. 1], while synthetic theanine is normally prepared as a racemic mixture of Land D-forms[2].

Theanine is responsible for a unique taste constituent of the tea, producing a caramel flavor and an attractive aroma and that helps to alleviate tea polyphenols astringency and caffeine bitterness[3]. Technical, safety and toxicological evaluation suggested that theanine is a safe and non-toxic photogenic food supplement. L-theanine was synthesized chemically for the first time from aqueous ethylamine and pyrrolidone carboxylic acid[4]. L-theanine has been studied as a food additive and functional food in relation to human nutrition. It has noticeable bioactivities including anti-cerebral ischemia-reperfusion injury, stress-reducing, antitumor, anti-aging, and anti-anxiety activities[5, 6]. Cooper[7] stated that dietary supplementation of L-theanine is a feasible way to mitigate reactive oxygen species [ROS]-induced damage.

Theanine is considered to be a unique amino acid in nature because, with the exception of being found in the basidiomycete mushroom Xerocomus badius, its occurrence appears to be limited to the Camellia genus, mostly the tea-producing plants C. sinensis var. sinensis and C. sinensis var. assamica and some closely related species such as C. japonica and C. sasanqua[8]In the leaves of the tea plant species, theanine accounts for about 500 g kg−1 of the free amino acids. Many of these amino acids are involved in producing the distinctive aroma and taste of tea and theanine has been linked with giving tea its distinctive umami taste[9]Because of its contribution to taste, the theanine content in tea leaves correlates highly with tea quality and price; the teas with a high content of theanine are normally evaluated as having a higher quality and thus command a higher price[10]. Theanine occurs in the cotyledons, shoots and roots of the tea plant seedling and it is biosynthesized from glutamic acid and ethylamine via the enzyme theanine synthetase[11].
