Ọkwa nri dị ọcha nke amino acid L-Theanine
Nkọwa ngwaahịa
L-Theanine ntụ ntụ sitere na Camellia sinensis - osisi tii. Black, akwụkwọ ndụ akwụkwọ ndụ, na tii ọcha niile sitere na Camellia sinensis osisi ma nyekwa ogige ahụ. L-Theanine bụ amino acid, mana ọ bụghị amino acid dị mkpa ma ọ bụ otu n'ime amino asịd na-adịghị mkpa nke ị nwere ike mara nke ọma.
Ọ bụ ezie na a na-aṅụ tii ruo ọtụtụ narị afọ ma na-atụgharị maka uru ya ruo ogologo oge, ọ bụ na 1949 ka a chọtara L-Theanine dị ka ihe mejupụtara tii tii. Ejila L-Theanine mee ihe n'ihe oriri na ihe ọṅụṅụ dị iche iche na Japan kemgbe 1960s. Ikekwe, ọ bụ ihe ijuanya, L-Theanine nwere ike inye ekpomeekpo umami (savory).
Ọ bụ amino acid soluble mmiri nke a na-ahụkarị na tii green, tii ojii, na ọtụtụ ero. Inweta amino acid a dị mma maka usoro ahụ ji alụso ọrịa ọgụ, ọrụ obi, ọrụ imeju. Ọ nwekwara ọrụ antioxidant nke na-enye nchebe megide nrụgide oxidative. anyị nwere ike ịnara theanine site na nri bara ụba nke theanine ma ọ bụ site na mgbakwunye nri dị.
L-Theanine bụ amino acid bụ isi a chọtara naanị na tii tii nke na-ahụ maka mgbakasị ahụ na ahụike nke anyị na-enwe mgbe anyị ṅụchara tii.
A na-ewere L-theanine dị ka amino acid na-abụghị nke nri, mana ọ ka nwere ike inye ọtụtụ uru nwere ike ịnweta mgbe agbakwunyere ya. Gụkwuo ka ịmatakwu banyere nootropic a yana otu ị ga-esi jiri ya kwalite cognition.
L-Theanine bụ amino acid dị mfe nke sitere na amino acid glutamine (Glutamine-ethylamine). Dị ka obere amino acid L-Theanine nwere ike ịgafe ihe mgbochi ọbara nke ụbụrụ yana na ụbụrụ mmadụ yana n'ime mkpụrụ ndụ akwara ndị ọzọ ọ na-emekọrịta ihe na onye na-anabata NMDA glutamate. L-Theanine dị ntakịrị belata uche na ọrụ nke onye na-anabata NMDA nke na-ebunye calcium (ụtọ cell) n'ime mkpụrụ ndụ akwara. Nke a bụ omume yiri nke a dị ka magnesium na-eme dị ka ihe nketa nke Calcium na-eduga n'ọgwụ ike akwara rand muscular. Ụdị omume etiti dị otú ahụ na-ewepụta ọtụtụ mmetụta na uru physiological anya na nke a na-ahụ anya. Dịka ọmụmaatụ, L-theanine, na-abawanye mpụta nke ebili mmiri alfa na ụbụrụ nke na-akwalite ịmụrụ anya na ntụrụndụ n'emeghị ka iro ụra.
