Abstract
Pigs liver esterase of 400-600 units of activity is prepd. by first extracting the liver with an organic solvent or solvent mixt, followed by the liquidisation of the liver in the presence of a buffer soln. The liq. is centrifuged. The esterase enzyme obtd. by this method is well suited for the enantio-selective hydrolysis of cyclopropane-carboxylic-acid-alkyl-esters which can be used as intermediates in the prepn of insecticide cpds.
