| Abstract |
The capacity for synthesizing 3β-sterols in Nassa spec. is investigated. The greater part of the acetate-1-14C administered was converted to carbon dioxide and incorporation of radioactivity into lipids amounted only to 0,34%. Within the lipids most radioactivity was present in phospholipids and glycerides. A small, but significant, radioactivity was present in the sterols, indicating that biosynthesis of sterols had taken place. Sterol composition is determined. Sterols with 27 carbon atoms are predominant. This preference is even still more pronounced in the sterolesters. Cholesterol is the principal sterol, but several other ones are present in addition. Sterol composition closely resembles those of other neogastropods. |
