Theanine yog ib tug dawb koob-zoo li tus siv lead ua crystal nrog ib tug melting point ntawm 217 degree thiab 218 degree thiab ib tug tshwj xeeb kev sib hloov ntawm \[ \]D20=0.7 degree . Theanine yog heev soluble nyob rau hauv dej, insoluble nyob rau hauv cov organic solvents xws li ethanol thiab ether, thiab nws cov aqueous kua yog me ntsis acidic, nrog ib tug caramel aroma thiab ib tug tshiab saj zoo li MSG, thiab ib tug saj pib ntawm 0.06%. .
Theanine yog absorbed nyob rau hauv cov hnyuv me, thiab tej zaum yuav absorbed nyob rau hauv cov hnyuv los ntawm methionine carrier system, los yog nws yuav muab ib tug Na-coupled co-transporter nrog glutamate. Tom qab theanine metabolized nyob rau hauv lub cev, tsis zoo theanine, glutamate thiab ethylamine raug kuaj pom hauv cov zis.
Theanine muaj ntau yam kev ua haujlwm ntawm lub cev thiab kev cia siab rau kev thov. Nws tuaj yeem cuam tshuam los ntawm cov ntshav-hlwb thaiv kev cuam tshuam ncaj qha rau lub hlwb kev ua haujlwm, cuam tshuam rau kev xav, thiab yuav muaj txiaj ntsig zoo rau tib neeg kev noj qab haus huv. Theanine kuj muaj cov nyhuv hypotensive, tuaj yeem txo cov ntsiab lus ntawm 5-hydroxytryptamine, thiab muaj cov nyhuv hypotensive ntawm cov nas muaj zog. Tsis tas li ntawd, txawm hais tias theanine nws tus kheej tsis muaj kev tiv thaiv qog nqaij hlav, nws tuaj yeem txhim kho kev ua tau zoo ntawm ntau yam tshuaj tiv thaiv qog.
Theanine muaj cov txiaj ntsig ntawm kev ua kom lub paj hlwb thiab so kom txaus. Nws tuaj yeem ua rau kom cov neurotransmitter dopamine nyob rau hauv mitochondria ntawm lub hlwb hlwb thiab cuam tshuam rau tib neeg txoj kev xav. Nws kuj tseem tuaj yeem txhawb cov tiam ntawm alpha nthwv dej, ua rau muaj kev xav zoo thiab zoo siab, thaum ua kom pom tseeb dua. Theanine muaj kev sib tw tiv thaiv kev tiv thaiv ntawm glutamate receptors thiab tiv thaiv cov ntaub so ntswg ntawm lub hlwb, uas tuaj yeem tiv thaiv lub paj hlwb tuag los ntawm cerebral ischemia.
Hauv kev lag luam zaub mov, theanine muaj ntau yam kev siv. Nws tuaj yeem siv los ua cov tshuaj yej ntsuab tsw txhim kho kom tsis txhob muaj qhov iab thiab astringency hauv lwm cov khoom noj thiab txhim kho tsw ntawm cov zaub mov. Piv txwv li, ntxiv theanine rau cocoa haus thiab barley tshuaj yej tuaj yeem txhim kho qhov tsw. Tsis tas li ntawd, theanine kuj muaj qhov poob phaus thiab tiv thaiv kev qaug zog.
