Specificity of a lipase from<i>Geotrichum candidum</i> for<i>cis</i>‐octadecenoic acid

Abstract

Abstract A lipase from Geotrichum candidum released mostly oleic acid from glyceryl 1‐elaidate‐2,3‐dioleate and very little trans fatty acid from margarine. When cod liver, Macadamia nut, peanut and safflower oils were substrates, the oleic acid content of the free acids was always in excess of the amount of the acid in the intact triglycerides. Congo palm oil was digested by both G. candidum and pancreatic lipases and the fatty acid compositions of the products of hydrolysis compared. The results obtained with the aid of G. candidum lipase tend to substantiate existence of some of the triglyceride isomers predicted from pancreatic lipase data.
