3-(cyclohexylamino)-2-hydroxy-1-propanesuhicic acid CAS:73463-39-5

CAPSO (3-(cyclohexylamino)-2-hydroxypropanesulfonic acid) bụ ihe nchekwa zwitterionic nke a na-ejikarị eme ihe na biochemistry na bayoloji molekul. A maara ya maka ikike nchekwa ya dị elu n'elu oke pH sara mbara ma a na-ewere ya dị ka ezigbo ihe nnọchi maka ihe nchekwa ndị ọzọ dịka MOPS na MES.

Isi ihe CAPSO na-arụpụta bụ ikike ya ịnọgide na-enwe gburugburu pH kwụsiri ike na nnwale ndị dị ndụ. Ọ na-arụ ọrụ site n'inye onyinye ma ọ bụ ịnakwere protons iji belata mgbanwe na pH nke asịd ma ọ bụ ntọala agbakwunyere kpatara. Uru pKa ya dị ihe dịka 9.8, nke na-eme ka ọ bụrụ ihe nchekwa dị irè maka nnwale na oke pH nke 8.2-9.6.

A na-ejikarị CAPSO eme ihe n'ọrụ dịka nhicha protein, nnwale enzyme, na electrophoresis. Nkwụsi ike ya na obere nnyonye anya na mmeghachi omume bayọlọji na-eme ka ọ baa uru maka ịnọgide na-enwe ọnọdụ kacha mma maka mmeghachi omume bayọlọji. Na mgbakwunye, a na-ejikarị CAPSO eme ihe maka ịmụ banyere njirimara protein bụ isi, mpịachi protein, na nkwụsi ike.
