In general, the composition of the blubber of the southern elephant seal, determined by gas–liquid chromatography, is similar to that of other marine mammals. In this regard, the present work disagrees with an earlier study made on an individual of this species. The marked disappearance of the long-chain polyunsaturated acids in both the nursing cow and fasting pup suggests catabolism of these acids during nonfeeding periods. Support is given here for the contention that some fatty acids are transferred intact from the depot fat of the seal cow to her pup via the milk.

SummaryFactor VII coagulant activity (FVIIc) is associated with an increased risk of fatal ischaemic heart disease (IHD). Several reports have suggested that dietary fat intake or hypertriglyceridaemia are associated with elevated levels of FVII. This study demonstrates that an intake of long-chain fatty acids sufficient to induce postprandial lipaemia in healthy subjects leads to a substantial elevation in both FVIIc and the concentration of FVII circulating in the activated form. Such an increase in FVIIc could not be induced by medium-chain triglycerides. These results suggest that the consumption of a sufficient amount of long-chain triglycerides to induce postprandial lipaemia induces the activation of FVII.
