I-Trometamol (Tris(Hydroxymethyl)aminomethane (Trometamol) ubumsulwa obuphezulu)

Izinhlobo zamakhemikhali

Ikristalu emhlophe noma i-powder. Incibilika ku-ethanol namanzi, incibilika kancane ku-ethyl acetate, i-benzene, ayincibiliki ku-ether, i-carbon tetrachloride, ithusi, imiphumela yokugqwala kwe-aluminium, iyacasula.

Izicelo

I-Tris, noma i-tris(hydroxymethyl)aminomethane, noma eyaziwa ngesikhathi sokusetshenziswa kwezokwelapha njenge-tromethamine noma i-THAM, iyinhlanganisela yezinto eziphilayo enefomula (HOCH2)3CNH2. Isetshenziswa kakhulu ku-biochemistry kanye ne-molecular biology njengengxenye yezixazululo ze-buffer njengakuma-TAE kanye nama-TBE buffers, ikakhulukazi izixazululo ze-nucleic acids. Iqukethe i-amine eyinhloko futhi ngaleyo ndlela ibhekana nokusabela okuhlobene nama-amine ajwayelekile, isb. ukuhlangana nama-aldehydes. I-Tris iphinde ihlanganise nama-ion ensimbi esixazululweni. Kwezokwelapha, i-tromethamine isetshenziswa ngezikhathi ezithile njengomuthi, onikezwa ekunakekelweni okujulile ngenxa yezakhiwo zayo njenge-buffer yokwelapha i-metabolic acidosis enzima ezimweni ezithile. Eminye imithi yakhiwe njenge-"tromethamine salt" kufaka phakathi i-hemabate (i-carboprost njengosawoti we-trometamol), kanye ne-"ketorolac trometamol".

Ifomu elibonakalayo
