ABSTRACT
A modified silicic acid technique was developed for separation of the lipids of bovine spermatozoa into seven distinct classes: saturated hydrocarbons, cholesterol esters, free cholesterol, triglycerides, diglycerides, monoglycerides, and phospholipids. The average lipid content of lyophilized spermatozoa was 11.05%. Monoglycerides and diglycerides were found in exceptionally large quantities, but no unsaturated hydrocarbons of free fatty acids could be detected.
