Isingeniso
I-DL-Theanine iyi-amino acid eyenzeka ngokwemvelo ekhishwe emaqabunga etiye. Ikhiqizwa isenzo se-catalytic se-asidi noma i-enzyme polyphenols futhi ine-isomers yemvelo ye-optical (L- kanye ne-D-isomers). Izindawo zokuhlala ezengeziwe e-DL-Theanine:
Ama-isomers abonakalayo: I-DL-Theanine iqukethe ama-L- kanye ne-D-isomers futhi iyingxube ye-achiral.
Ukunyibilika: I-DL-Theanine incibilika kahle emanzini futhi iyancibilika ku-ethanol, kodwa inokuncibilika okuphansi.
Ukuzinza: I-DL-Theanine izinzile ngaphansi kwezimo ezingathathi hlangothi noma ezine-asidi ebuthakathaka, kodwa yonakaliswa kalula ngaphansi kwezimo ze-alkaline.
I-Antioxidant: I-DL-Theanine inganciphisa ama-radicals mahhala, inomsebenzi onamandla we-antioxidant, futhi inomphumela omuhle ekubambezeleni ukuguga nokumelana nokucindezeleka okwenziwe nge-oxidative.
I-Nutraceuticals: I-DL-Theanine ingasetshenziswa njengesengezo sokudla okunempilo ukusiza ukuthuthukisa ukusebenza kwamasosha omzimba nokukhuthaza impilo.
Izindlela zokulungiselela ze-DL-theanine ikakhulukazi zifaka indlela ye-asidi nendlela ye-enzymatic. Indlela ye-asidi ukubola i-polyphenols yetiye ibe yi-theotic acid nama-amino acid ngokuphendula amaqabunga etiye nama-acids, bese uthola i-DL-theanine ngochungechunge lokukhipha, i-crystallization nezinye izinyathelo. Indlela ye-enzymatic iwukusebenzisa ama-enzyme athile ukugqugquzela ukusabela ekuboliseni ama-polyphenols etiye libe ama-amino acid, bese ikhipha futhi ihlanze ukuze kutholwe i-DL-theanine.
Kubantu abane-allergies noma izifo ezikhethekile, kufanele isetshenziswe ngaphansi kokuqondisa kukadokotela noma uchwepheshe.
