During fat absorption, unsaturated long chain fatty acids are esterified at a higher rate than saturated fatty acids of similar chain length. This phenomenon has been attributed to differences in the binding affinity of fatty acids to a cytosolic fatty acid-binding protein. As intestinal mucosa utilizes plasma free fatty acids as well, we investigated… (More)
FIG. 1. Uptake of 3H-palmitic and 14C-linoleic acid by intestinal mucosa from plasma. 3H-palmitic and 14C-linoleic acid, complexed to rat serum, were injected acutely i.v., and 3H and 14C was measured in intestinal mucosal homogenates (see Methods) at the times indicated. Each point represents the mean of at least 10 experiments, the vertical lines indicate the Standard Error.
