Phofo ea L-Tyrosine
l-tyrosine
selelekela se sekhutšoanyane
Tyrosine (e khutsufalitsoeng e le Tyr kapa Y) kapa 4-hydroxyphenylalanine ke e 'ngoe ea li-amino acid tse 22 tse sebelisoang ke lisele ho kopanya liprotheine. E ka sebelisoa ho kopanya liprotheine liseleng, ka li-codon UAC le UAU. Ke amino acid e seng ea bohlokoa e nang le lihlopha tsa mahlakoreng a polar 'me e ka hlahisoa ke' mele oa motho. Lentsoe 'tyrosine' le tsoa ho tyros ea Segerike, e bolelang chisi. Mathoasong a lekholo la bo19 la lilemo, e ile ea fumanoa ka lekhetlo la pele ke setsebi sa k'hemistri sa Jeremane Eustus von Libich ka chisi ea casein, 'me ha e sebelisoa e le sehlopha se sebetsang kapa se ka thoko, e bitsoa tyrosine.
mosebetsi
Ntle le ho ba amino acid ea protheine, tyrosine e bapala karolo e ikhethang phetisong ea matšoao liprotheineng ka ho itšetleha ka lihlopha tse sebetsang tsa phenolic. Mosebetsi oa eona ke ho amohela lihlopha tsa phosphate tse fetisetsoang ke li-protein kinase (tse bitsoang li-receptor tsa tyrosine kinase), ha phosphorylation ea lihlopha tsa hydroxyl e fetola ts'ebetso ea protheine e reriloeng.
Tyrosine e boetse e bapala karolo ea bohlokoa ho photosynthesis, e sebeletsa e le mofani oa lielektrone ho fokotseng karabelo ea chlorophyll e nang le oxidized ho li-chloroplast (Photosystem II), ho tlosoa ha protonation ea lihlopha tsa phenolic OH, 'me qetellong e fokotsoe ke lihlopha tse' nè tsa mantlha tsa manganese ho Photosystem II.
Mehloli ea lijo
Tyrosine e ka etsoa ho tsoa ho phenylalanine 'meleng' me e ka fumanoa lijong tse ngata tse nang le protheine e ngata joalo ka khoho, kalakuni, tlhapi, lebese, yogurt, chisi, chisi, linate tsa peanut, lialmonde, peo ea mokopu, sesame, soya, linaoa tsa lima, li-avocado le libanana.
L-tyrosine ke amino acid e seng ea bohlokoa 'me ke e' ngoe ea lintho tsa bohlokoa tseleng ea metabolism ea methionine. E fumaneha haholo linthong tse phelang 'me e bapala karolo ea bohlokoa lits'ebetsong tse ngata tsa baeloji.
L-tyrosine ke karolo ea liprotheine 'me e nka karolo ts'ebetsong ea ho kopanya liprotheine. Hape ke selelekela sa lintho tse fapaneng tse sebetsang, ho kenyeletsoa le li-neurotransmitters tsa catecholamine tse kang dopamine, norepinephrine, le adrenaline, hammoho le lihormone tsa thyroid le melanin.
Ho phaella moo, L-tyrosine e boetse e ameha tlhahisong ea limolek'hule tsa bohlokoa tsa baeloji ka letoto la lienzyme 'meleng, tse kang tyrosine kinase le tyrosine hydroxylase, tse amehang litseleng tsa lipontšo tsa kinase le taolong ea fisioloji.
Ho ja L-tyrosine ho ka fumanoa ka lijo, ka mehloli e mengata ea lijo ho kenyeletsoa linate, peo, nama, tlhapi le lihlahisoa tsa lebese. Ho phaella moo, L-tyrosine e ka boela ea fetoloa ho tsoa ho amino acid e 'ngoe, phenylalanine, ka tsela ea tlhahiso ea tyrosine 'meleng.
