Uhlolojikelele:Igama lomkhiqizo we-Tris yi-tris(hydroxymethyl)aminomethane;i-tromethamine;i-tromethamine;2-amino-2-(hydroxymethyl) -1,3-propanediol.Kuyikristalu emhlophe noma impushana.Incibilika ku-ethanol nasemanzini, inyibilika kancane ku-ethyl acetate ne-benzene, ayincibiliki ku-ether ne-carbon tetrachloride, igqwala iye kwikhopha ne-aluminium, namakhemikhali acasulayo.
Izinkomba:I-Tromethamine iyisisekelo se-amino-free amino buffer base-sodium, esabela ne-H2CO3 oketshezini lomzimba ukunciphisa i-H2CO3 futhi ikhiqize i-HCO32- ngesikhathi esifanayo.Ingakwazi ukumunca ama-ion e-hydrogen futhi ilungise i-acidemia.Iqinile, futhi ingangena kulwelwesi lweseli, evame ukusetshenziswa ku-acute metabolism ne-accidemia yokuphefumula.
Izakhiwo zokubhafa:I-Tris isisekelo esibuthakathaka esine-pKa engu-8.1 ku-25°C;ngokuya ngethiyori yebhafa, uhla olusebenzayo lokubhafa lwe-Tris buffer luphakathi kwe-pH 7.0 kanye no-9.2.I-pH yesisombululo esinamanzi se-Tris base icishe ibe ngu-10.5.Ngokuvamile, i-hydrochloric acid iyengezwa ukuze kulungiswe inani le-pH enanini elifiswayo, bese kutholakala isisombululo sebhafa esinenani le-pH.Kodwa-ke, kufanele kuqashelwe umphumela wezinga lokushisa ku-pKa ye-Tris.
Isicelo:I-Tris isetshenziswa kabanzi ku-acute metabolic kanye ne-accidemia yokuphefumula.Kuyi-alkaline buffer futhi inomphumela omuhle wokuvimbela ku-metabolic acidosis kanye nomsebenzi we-enzymatic.I-Tris ivamise ukusetshenziswa njengebhafa yebhayoloji futhi ivamise ukwakhiwa ngamavelu e-pH angu-6.8, 7.4, 8.0, kanye no-8.8.Ifomula yayo yesakhiwo kanye nenani le-pH liyahlukahluka kakhulu ngezinga lokushisa.Ngokuvamile i-Chemicalbook ithi kuwo wonke amadigri akhuphuka izinga lokushisa, i-pH yehla ngo-0.03.I-Tris isetshenziswa kakhulu ekulungiseni izigcinalwazi ekuhlolweni kwebhayoloji ye-biochemical kanye ne-molecular biology.Isibonelo, i-Tris iyadingeka kuwo womabili amabhafa we-TAE kanye ne-TBE (ekuhlanganisweni kwama-nucleic acid) avame ukusetshenziswa ekuhloleni kwamakhemikhali ezinto eziphilayo.Njengoba iqukethe iqembu lama-amino, ingabhekana nokusabela kwe-condensation nge-aldehydes.
