L-Tyrosine
Iikristal ezimhlophe okanye i-crystalline powder.Inyibilika ngokukhululekileyo kwi-formic acid, inyibilika kancinane kakhulu emanzini, ayinyibiliki kwi-ethanol nakwi-ether.Ukunyibilika kwi-dilute hydrochloric acid kunye ne-dilute nitric acid.Ngaphandle kokuba yiproteinogenic amino acid, i-tyrosine inendima ekhethekileyo ngenxa yokusebenza kwephenol.Kwenzeka kwiiprotheni eziyinxalenye yeenkqubo zokudluliselwa kwemiqondiso.I-functio ns njengomamkeli wamaqela e-phosphate athi adluliselwe ngendlela yeprotein kinases (ebizwa ngokuba yi-receptor tyrosine kinases).I-Phosphorylation yeqela le-hydroxyl iguqula umsebenzi weprotheni ekujoliswe kuyo.
