L-tyrosine
sumo pfupi
Tyrosine (yakapfupikiswa seTyr kana Y) kana 4-hydroxyphenylalanine imwe ye22 amino acids inoshandiswa nemasero kugadzira mapuroteni.Inogona kushandiswa kugadzira mapuroteni mumasero, ane macodon UAC uye UAU.Iyo isiri yakakosha amino acid ine polar mativi mapoka uye inogona kugadzirwa nemuviri wemunhu.Izwi rokuti 'tyrosine' rinobva muchiGiriki tyros, zvinoreva chizi.Mukutanga kwezana ramakore rechi 19, yakatanga kuwanikwa neGerman chemist Eustus von Libich mune casein cheese, uye kana yakashandiswa seboka rinoshanda kana parutivi, inonzi tyrosine.
basa
Pamusoro pekuva puroteni amino acid, tyrosine inobata basa rakakosha mukushandurwa kwechiratidzo mumapuroteni nekuvimba nemapoka ephenolic anoshanda.Basa rayo nderekugamuchira kwemapoka ephosphate anotamiswa neprotein kinases (inonzi tyrosine kinase receptors), nepo phosphorylation yemapoka e-hydroxyl inoshandura basa reprotein yakanangwa.
Tyrosine inoitawo basa rakakosha mu photosynthesis, ichishanda semupi wemagetsi mukuderedza kuita kweoxidized chlorophyll muma chloroplasts (Photosystem II), deprotonation yephenolic OH mapoka, uye pakupedzisira kuderedzwa nemasumbu mana epakati manganese muPhotosystem II.
Zvinyorwa zvekudya
Tyrosine inogona kugadzirwa kubva ku phenylalanine mumuviri uye inogona kuwanikwa mune zvakawanda zveprotein zvekudya zvakaita sehuku, turkey, hove, mukaka, yogati, chizi, chizi, nzungu, maarumondi, mhodzi dzenhanga, sesame, soya bhinzi, lima bhinzi, avocados. uye mabanana.
L-tyrosine isiri yakakosha amino acid uye chimwe chezvinhu zvakakosha mumethionine metabolism nzira.Inowanikwa zvakanyanya muzvisikwa uye inoita basa rakakosha mune akawanda biological process.
L-tyrosine inhengo yeprotein uye inobatanidzwa mukugadzirwa kweprotein.Iyo zvakare inotungamira yezvakasiyana bioactive zvinhu, zvinosanganisira catecholamine neurotransmitters senge dopamine, norepinephrine, uye adrenaline, pamwe neiyo thyroid mahormone uye melanin.
Uye zvakare, L-tyrosine inobatanidzwawo mukuumbwa kweakakosha mamorekuru ehupenyu kuburikidza neakatevedzana ma enzymes mumuviri, senge tyrosine kinase uye tyrosine hydroxylase, iyo inobatanidzwa mukinase yekusaina nzira uye physiological regulation.
Kudya kweL-tyrosine kunogona kuwanikwa kuburikidza nekudya, kune zvakawanda zvekudya zvinosanganisira nzungu, mhodzi, nyama, hove, uye zvigadzirwa zvemukaka.Mukuwedzera, L-tyrosine inogonawo kushandurwa kubva kune imwe amino acid, phenylalanine, kuburikidza ne tyrosine synthesis nzira mumuviri.
