I-3-Morpholino-2-hydroxypropanesulfonic acid ityuwa yesodium, eyaziwa ngokuba yityuwa yesodium ye-MES, yikhompawundi yemichiza esetyenziswa ngokuqhelekileyo njenge-buffering kuphando lwebhayoloji kunye ne-biochemical.
I-MES sisithinteli se-zwitterionic esisebenza njengomlawuli we-pH, egcina i-pH izinzile kwiinkqubo ezahlukeneyo zovavanyo.Inyibilika kakhulu emanzini kwaye inexabiso le-pKa elimalunga ne-6.15, nto leyo iyenza ilungele ukugqunyelelwa kuluhlu lwe-pH lwe-5.5 ukuya kwi-7.1.
Ityuwa yesodium ye-MES isetyenziswa rhoqo kubuchule bebhayoloji yemolekyuli njenge-DNA kunye ne-RNA yodwa, uvavanyo lwe-enzyme, kunye nokucocwa kweprotheyini.Ikwasetyenziswa kwimidiya yenkcubeko yeseli ukugcina indawo ezinzileyo ye-pH yokukhula kweeseli kunye nokwanda.
Enye into ephawulekayo ye-MES kukuzinza kwayo phantsi kweemeko ze-physiological kunye nokuchasana nokutshintsha kweqondo lokushisa.Oku kuyenza ilungele ukusetyenziswa kwimifuniselo apho kulindeleke ukuguquguquka kobushushu.
Abaphandi bahlala bekhetha ityuwa yesodium ye-MES njengesithinteli ngenxa yokuphazamiseka okuncinci kokusabela kwe-enzymatic kunye nomthamo ophezulu we-buffer ngaphakathi koluhlu lwe-pH olufanelekileyo.
