title: Limited fat absorption in the large intestine of mice. A morphological study.
abstract: A limited fat-absorbing ability of the epithelial cells in the cecum and colon of mice was demonstrated light- and electron-microscopically. After injection of predigested donor fat into ligated segments of the large intestine and after massive gastric intubation of fat, fat droplets, predominantly of extremely large diameter, were visible in the cecum and colon. Comparison with fat absorption in the proximal and distal small intestine was undertaken. The large intestine, similar to the distal small intestine, is capable of absorbing lipids; however, the subsequent processing of fat appears considerably less effcient than in the proximal segments of the small intestine.
