Distribution of ¹⁴C-and ³H- free cholesterol and cholesteryl ester in the intestinal wall in rats. These data are from the extracts of the intestines in Figure 4B. ¹⁴C was originally delivered as ¹⁴C-free cholesterol and ³H as ³H-cholesteryl oleate with both radiolabels on the cholesterol moiety. ¹⁴C- and ³H-free cholesterol are shown in (A). ¹⁴C- and ³H-cholesteryl ester are shown in (B). Values are mean±s.e.mean, n=5 per group. ^**P<0.01; ^***P<0.001.
