Occurrence of 7‐methyl‐7‐hexadecenoic acid, the corresponding alcohol, 7‐methyl‐6‐hexadecenoic acid, and 5‐methyl‐4‐hexadecenoic acid in sperm whale oils
Abstract Two sperm whale oils from the northern hemisphere and two from the southern hemisphere were fractionated. Triglyceride and wax esters were examined for fatty acids and alcohols with monoethylenic unsaturation bearing a methyl branch on an ethylenic carbon. The 7‐methyl‐7‐hexadecenoic acid (...
