Abstract

1. 1. The parent vegetable polyenoic acids and their long-chain animal metabolites have been studied in liver and brain phospholipids in a herbivorous mammal (Kob) and a carnivore (Hyaena) of similar body size, but contrasting developments of the nervous system. 2. 2. The fatty acid patterns of the phospholipids were found to be tissue and species specific. 3. 3. The major metabolite of linolenic acid was docosapentaenoate (C22:5,n-3) in the Kob liver, but docosahexaenoate (C22:6,n-3) in the Hyaena. Brain grey matter of both species contained the hexaenoate. 4. 4. Comparative studies from 30 different species demonstrated that the brain ethanolamine phosphoglycerides (EPG) had a relatively constant fatty acid composition despite wide variations in the fatty acid composition of liver EPG.
