Adult male, chow-fed Sprague-Dawley rats were given intraduodenally a bolus of emulsion of 0.5 ml of fish oil (MaxEPA) or olive oil plus 0.5 ml of 20 mM sodium taurocholate. Intestinal lymph was collected from a cannula in the main intestinal lymph trunk for various times after oil administration. There was no difference in the absorption of either type of oil over 6 and 24 h, over which times about 40 and 70% of the administered dose was taken up. For MaxEPA, the flux of triacylglycerols remained at a basal level of 0.07 mumol/min for 30 min, after which it rose rapidly to a maximum of 0.87 mumol/min between 90 and 120 min. The flux was 0.4 mumol/min for the subsequent 4 h. After 30 min, the composition of the lymph triacylglycerols began to change to show the presence of large proportions of fatty acyl chains that were characteristic of fish oil, especially eicosapentaenoate (20:5(n-3] and docosahexaenoate (22:6(n-3]. The composition of the lymph remained fairly similar to that of the fish oil for up to 6 h, the last time point at which detailed analysis was done. The docosahexaenoate in the triacylglycerols of the fish oil was primarily in the sn-2 position of glycerol, whereas a more random distribution of eicosapentaenoate over all glycerol positions was found. The positional distribution of the acids in the lymph triacylglycerols was similar to that in the fish oil. There was no evidence of substantial chain elongation or shortening during absorption. The results indicate that fish oil is effectively absorbed from the rat intestine without substantial alteration in the acyl chains of the triacylglycerols.
