Specificity of lipase from several seeds and<i>Leptospira pomona</i>

Abstract

Abstract The specificities of lipase preparation from oats, Leptospira pomona DM 2 H, corn, soybeans, safflower seed and pinion nuts were examined by using cocoa butter, lard and corn oil as substrates. Oat lipase exhibited an acyl group specificity, favoring the hydrolysis of linoleyl groups and discriminating against stearoyl groups. The L. pomona lipase exhibited a tendency to hydrolyze acyl groups on the 1 and 3 positions of glycerol preferentially. The hydrolysis by the other seed lipases was nonspecific.
