I-L-Histidine
Intshayelelo
Uhlobo lwemveliso ye-L-hertidine yikristale emhlophe engumgubo. Yinto ebalulekileyo ye-amino acid eluhlaza. Yi-amino acid engabalulekanga emzimbeni womntu. Isetyenziswa kakhulu njengezinto eziluhlaza zokufaka i-amino acid kunye ne-amino acid yomlomo. Ukongeza, ikwaliyeza elibalulekileyo lokunyanga isifo sentliziyo, i-anemia, i-rheumatoid arthritis, izilonda zesisu kunye ne-hepatitis enkulu. Isetyenziswa ngakumbi kwicandelo lezonyango.
Iimpawu zekhemikhali
Iikristale ezimhlophe okanye umgubo wekristale. Ikrakra kancinci. Iyanyibilika kwaye ibole malunga ne-277 ~ 288℃. Iqela layo le-imidazole kulula ukwenza iityuwa ezintsonkothileyo ezinee-ion zesinyithi. Inyibilika emanzini (4.3g/100ml, 25℃), kunzima kakhulu ukuyinyibilikisa kwi-ethanol, ayinyibiliki kwi-ether.
SEBENZISA
I-L-Histidine ingasetyenziswa njengesongezelelo sesondlo, isinongo kunye nesiphuculi sesondlo. Yinto ebalulekileyo ekufakweni kwe-amino acid kunye nokulungiswa kwe-amino acid enzima. Ingasetyenziselwa ukunyanga izilonda zesisu. Ikwasetyenziselwa uphando lwe-biochemical.
