TianJia Yongera Ibiryo Byakozwe L-Tyrosine
l-tyrosine
Intangiriro
Tyrosine (mu magambo ahinnye yitwa Tyr cyangwa Y) cyangwa 4-hydroxyphenylalanine ni imwe muri 22 aside amine ikoreshwa na selile mu guhuza poroteyine.Irashobora gukoreshwa muguhuza poroteyine muri selile, hamwe na codons UAC na UAU.Ni aside amine idakenewe irimo amatsinda ya polar kandi irashobora guhuzwa numubiri wumuntu.Ijambo 'tyrosine' rikomoka mu kigereki tyros, bisobanura foromaje.Mu ntangiriro z'ikinyejana cya 19, yavumbuwe bwa mbere n'umuhanga mu by'imiti w’umudage Eustus von Libich muri foromaje ya foromaje, kandi iyo ikoreshejwe nk'itsinda rikora cyangwa uruhande, ryitwa tyrosine.
imikorere
Usibye kuba aside amine aside, tyrosine igira uruhare runini mugukwirakwiza ibimenyetso muri poroteyine zishingiye ku matsinda akora ya fenolike.Imikorere yacyo nkiyakira amatsinda ya fosifate yimurwa na protein kinase (ibyo bita tyrosine kinase reseptors), mugihe fosifora yo mumatsinda ya hydroxyl ihindura ibikorwa bya poroteyine yagenewe.
Tyrosine kandi igira uruhare runini muri fotosintezez, ikora nka electron mugutanga reaction yo kugabanya chlorophyll ya okiside muri chloroplasts (Photosystem II), gutesha agaciro amatsinda ya OH ya fenolike, hanyuma amaherezo igabanywa nibice bine byingenzi bya manganese muri Photosystem II.
Inkomoko y'ibiryo
Tyrosine irashobora gushirwa muri fenylalanine mu mubiri kandi irashobora kuboneka mu biribwa byinshi bya poroteyine nyinshi nk'inkoko, inkeri, amafi, amata, yogurt, foromaje, foromaje, ibishyimbo, almonde, imbuto y'ibihaza, sesame, soya, ibishyimbo bya lima, avoka, n'ibitoki.
L-tyrosine ni aside amine idakenewe kandi ni kimwe mu bintu by'ingenzi mu nzira ya methionine metabolism.Iraboneka cyane mubinyabuzima kandi igira uruhare runini muburyo butandukanye bwibinyabuzima.
L-tyrosine ni kimwe mu bigize poroteyine kandi igira uruhare mu guhuza poroteyine.Nibibanziriza ibintu bitandukanye bioactive, harimo catecholamine neurotransmitters nka dopamine, norepinephrine, na adrenaline, hamwe na hormone ya tiroyide na melanin.
Byongeye kandi, L-tyrosine igira kandi uruhare mu guhuza molekile zikomeye z’ibinyabuzima binyuze mu ruhererekane rw’imisemburo mu mubiri, nka tyrosine kinase na hydroxylase ya tyrosine, igira uruhare mu kwerekana ibimenyetso bya kinase no kugenzura umubiri.
Kunywa L-tyrosine birashobora kuboneka binyuze mu ndyo, hamwe n’ibiribwa byinshi birimo imbuto, imbuto, inyama, amafi, n’ibikomoka ku mata.Byongeye kandi, L-tyrosine irashobora kandi guhindurwa ikava muyindi aside amine, fenylalanine, ikoresheje inzira ya synthesis ya tyrosine mu mubiri.
