In VitroStimulation by Parathion of Porcine Pancreatic Carboxylesterase Activity toward Triacetin

Effect of Unsaponifiable Lipid Components from the Red AlgaPorphyra teneraon Pancreatic Carboxylesterase Activity toward TriacetinIn Vitro

“…We have thus far studied the isolation and characterization of the activator, which stimulates markedly the hydrolysis of triacetin (TAesterase activity) by a porcine pancreatic lipase preparation, from the marine brown alga Hizikia fusiformis (hiziki).l -8) It has been found that phytol 6 ) isolated from hiziki is a typical activator of this kind, and recently that parathion 9 ) as well as retinol 10 ) exhibits a remarkable stimulating action, essentially similar to that observed with phytol, on the TAesterase activity.…”
