Abstract
Summary
A stable olive oil emulsion has been described. Using this new emulsion the lipase activity of a series of biological materials have been studied. Sera of different mammals showed different lipase activities. Sera of some species had a wide range of activity, whereas, those of others had no activity. Wheat germ “lipase” splits olive oil only slightly. Highly purified plasma cholin-esterase was almost inert indicating that this enzyme is not involved in fat digestion. Hemoglobin is a powerful inhibitor, and Lima bean inhibitor, a powerful activator of serum lipase. A method for demonstrating anti-lipase in serum has been presented. It is well known that normal human serum and the serum of most other mammals do not contain a specific lipase similar to pancreatic lipase. The hydrolysis of olein described in this paper is affected by another type of enzyme. For convenience the term lipase has been employed in this paper.
