Abstract The presence in Northern Pike ( Esox locius ) liver and testes lipids of a group of eight homologous fatty acids of as yet unknown structure is reported. They occur esterified to cholesterol and to glycerol as triglycerides but are absent from the phospholipids. They contain three oxygens and are characterized further by being more resistant to hydrogenation than normal unsaturated fatty acids and by an inability to form urea inclusion compounds. They also have been found to be major constituents of the liver fatty acids of four additional species of fish.
