Kodi kutenga theanine kumachita chiyani?

Chani Ines Theaninndi?

Theanine ndi amino acid yokhala ndi kuchuluka kwakukulu mu tiyi, yomwe imaposa 50% ya ma amino acid onse aulere. Kuchuluka kwa theanine kumasiyana malinga ndi mtundu ndi gawo la tiyi. Theanine ndi 1%-2% ya kulemera kwa tiyi wouma.

Tiyi ya theanine, yomwe imadziwikanso kuti glutamic acid γ-ethylamide, ndi amino acid yopanda mapuloteni yomwe imapezeka mu tiyi. Inayamba kupangidwa kuchokera ku tiyi wobiriwira mu 1950. Ili ndi kukoma kokoma komanso kwatsopano ndipo imachepetsa kuwawa komwe kumachitika chifukwa cha caffeine ndi CatechinNdi imodzi mwa ma amino acid omwe amapezeka mu tiyi, ndipo ndi pafupifupi 50%-60% ya ma amino acid onse omwe amapezeka mu tiyi.

Theanine yopangidwa mwachilengedwe ndi ya mtundu wa L, pomwe theanine yambiri yopangidwa ndi yosakaniza ya mtundu wa D ndi mtundu wa L; chifukwa cha mawonekedwe osiyanasiyana, ntchito ya D-theanine m'thupi ndi yotsika kwambiri, pomwe ntchito ya L-type ndi yapamwamba.

Theanine ili ndi ntchito zambiri zokhudzana ndi zamoyo, monga kuchepetsa kutopa, kuteteza maselo amitsempha, kuletsa okosijeni, kuchepetsa nkhawa, komanso kutonthoza mitsempha. Nthawi yomweyo, theanine imakhalanso ndi zotsatira zolimbikitsa kukula kwa maselo a muubongo, kukonza magwiridwe antchito a ubongo, kupha mabakiteriya komanso kupha kutupa.

Chani KodiThe NtchitoZa Theanine?

1. Kuchepetsa kuthamanga kwa magazi

Kuthamanga kwa magazi ndi matenda ofala masiku ano omwe angayambitse kuchuluka kwa ma catecholamines m'thupi la munthu, zomwe zimayambitsa kutsekeka kwa magazi, kuchuluka kwa mtima, komanso mavuto ena okhudzana ndi izi. Kuyesera pa momwe L-theanine imakhudzira kuthamanga kwa magazi kwa anthu omwe ali ndi vuto la kupsinjika kukuwonetsa kuti theanine sikuti imangochepetsa nkhawa, komanso imaletsa kwambiri kuwonjezeka kwa kuthamanga kwa magazi mwa anthu omwe ali ndi vuto la kupsinjika kwambiri.

2. Kuchepetsa thupi

Theanine imatha kuchepetsa mafuta m'thupi. Kafukufuku akusonyeza kuti atapatsa mbewa zazikazi mitundu yosiyanasiyana ya theanine kwa milungu 16, adapeza kuti pamene kuchuluka kwa theanine kunali 0.04%, kumatha kuchepetsa kulemera kwa thupi ndi kuchuluka kwa mafuta m'thupi la mbewa. Kuphatikiza apo, kafukufukuyu adapezanso kuti theanine imatha kuletsa bwino kufalikira kwa maselo a chiwindi chifukwa cha aminogalactose ndikuletsa lipid peroxidation, potero kubwezeretsa mphamvu ya antioxidant ya maselo a chiwindi.

3. Kuletsa kutopa

Malinga ndi malo osiyanasiyana opangira, kutopa kochita masewera olimbitsa thupi kumagawidwa m'mitundu iwiri: kusintha kwa ma neurotransmitters ndi njira zokhudzana ndi kupanga kutopa kwapakati, pomwe kutopa kwa zinthu zogwira ntchito m'thupi ndi kuchuluka kwa ma metabolites kumabweretsa mwachindunji kutopa kwa m'mphepete. Theanine imatha kuchepetsa kutopa, ndipo njira yake ikhoza kukhala yogwirizana ndi mfundo yakuti theanine imatha kuwonjezera kuchuluka kwa ma neurotransmitters oyambitsa kukwiya, kuchepetsa kuchuluka kwa ma neurotransmitters oletsa ndikulimbikitsa ntchito ya ma glutamate receptors.

4. Kulimbitsa chitetezo chamthupi

Kafukufuku wasonyeza kuti L-theanine imatha kuchepetsa kutsekeka kwa chitetezo chamthupi komwe kumachitika chifukwa cha kuchita masewera olimbitsa thupi kwambiri komanso kupewa chimfine ndi fuluwenza mwa kuwonjezera chitetezo chamthupi. Nthawi yomweyo, kafukufuku wambiri wa maselo ndi nyama wasonyeza kuti theanine imatha kukhala ndi gawo lothandizira chitetezo chamthupi pakutupa, kuwonongeka kwa mitsempha, ndi matumbo mwa kuwongolera ntchito ya ma lymphocyte a γδT, kapangidwe ka glutathione (GSH), komanso kutulutsa ma cytokines ndi ma neurotransmitters.

Kodi Kugwiritsa Ntchito N'chiyani? Theanine?

1. Chowonjezera kukoma kwa chakudya

Theanine ili ndi kukoma kwatsopano komanso kotsitsimula. Kuiyika mu zakumwa za tiyi kungathandize kukulitsa kukoma kwa zakumwa za tiyi. Kuonjezera theanine mu zakumwa za koko, tiyi wa barele, khofi, zakumwa za ginseng, mowa ndi zakumwa zina kungathandizenso kwambiri kukulitsa kukoma popanda kusokoneza kukoma.

2. Zowonjezera pazakudya zogwira ntchito

Theanine imawonjezera mphamvu ya mafunde a alpha muubongo, kupangitsa anthu kumva omasuka komanso kukumbukira bwino, ndipo yatsimikiziridwa ndi mayesero a anthu. Kafukufuku wasonyeza kuti kuwonjezera theanine mu maswiti, zakumwa zosiyanasiyana, ndi zina zotero kungapangitse kuti munthu akhale ndi mphamvu yopumula.

Kupanga CHONSEf Theanine

Njira yopangira Theanine mu mitengo ya tiyi

Theanine imapangidwa mwachindunji kuchokera ku L-glutamic acid ndi ethylamine motsogozedwa ndi theanine synthase. Pakati pawo, pali njira ziwiri zopangira L-glutamic acid, yomwe ndi yoyambira theanine biosynthesis, mu mitengo ya tiyi, zomwe zimapangitsanso kuti njira zopangira theanine zisiyane m'mitengo ya tiyi. Njira imodzi ndi GDH, ndiko kuti, α-ketoglutarate ndi ammonia zimapanga glutamate motsogozedwa ndi glutamate dehydrogenase; ina ndi njira ya GS/GOGAT, ndiko kuti, L-glutamate ndi ammonia zimapanga glutamine motsogozedwa ndi glutamine synthetase, ndipo glutamine ndi α-ketoglutarate zimapanga mamolekyu awiri a L-glutamate motsogozedwa ndi glutamate synthetase.

Kukonzekera ndi kupanga kwa theanine

Pakadali pano, theanine imachokera makamaka ku kapangidwe ka mankhwala, kuyaka kwa ma enzyme achilengedwe komanso kuchotsa tiyi kuchokera ku mitengo ya tiyi yachilengedwe. Kupanga mankhwala ndi njira imodzi yomwe imagwiritsidwa ntchito kwambiri masiku ano. Njirayi imatha kupeza L-theanine yokhala ndi chiyero cha pafupifupi 90%, ndipo mtengo wake ndi wotsika mtengo. Poganizira za kupanga kwa L-theanine padziko lonse lapansi, kupanga mankhwala kumakhala kwakukulu, kutsatiridwa ndi kuyaka kwa ma enzyme achilengedwe, ndipo kuchotsa kwachilengedwe kumakhala kochepa kwambiri.
