L-tytrosine
Ama-crstal amhlophe noma i-crystalline powder. Ukuncibilika ngokukhululeka ku-formic acid, kuncibilike kakhulu emanzini, empeleni ku-infoluble e-ethanol nakwether. Chaza nge-dilute hydrochloric acid kanye ne-dilute nitric acid. Ngaphandle kokuba yiproteinogenic amino acid, i-tyrosine inendima ekhethekile ngenxa yokusebenza kwe-phenol. Kwenzeka kumaprotheni ayingxenye yezinqubo zokudluliselwa kwesiginali. It functio ns njengomukeli wamaqembu we-phosphate adluliselwa ngendlela yama-protein kinases (okuthiwa yi-receptor tyrosine kinases). I-phosphorylation yeqembu le-hydroxyl ishintsha umsebenzi wamaprotheni okuhlosiwe.
