O le a le HEPES CAS 7365-45-9?

HEPES CAS 7365-45-9 ua fa'amatalaina o se tasi o fa'apolopolo sili ona lelei mo fa'amoemoega uma o lo'o avanoa mo su'esu'ega olaola. I le biological pH, o le mole o le zwitterionic, ma e aoga e avea o se pa puipui i le pH 6.8 i le 8.2 (pKa 7.55). E masani ona faʻaaogaina i le aganuʻu sela i le faʻatonuga i le va o le 5mM i le 30 mM. Ua fa'aogaina le HEPES i le tele o fa'aoga eseese, e aofia ai le aganu'u a le tino. E masani ona fa'aoga e fa'afefe ai le fa'asalalauga tu ma aga i le ea. E maua e le HEPES lona fa'aogaina i su'esu'ega in vitro ile Mg.
