a monolayer reaction system employing tripropionin and siliconized glass beads was used to study the effects of taurodeoxycholate and colipase on the catalytic activity , interfacial stability , and interfacial affinity of porcine pancreatic lipase b ( ec 3.1.1.3 ) the stability and catalytic activity of lipase at the bead-water interface are governed by the same two ionizable groups with pka values ( in the absence of cofactors ) of 5.6 and 9.3 .
