摘要：

Cholesterol and lecithin absorption in man was studied by intestinal intubation. β3H-sitosterol lipid-soluble marker. Cholesterol absorption was limited and progressed over the length of the small intestine; most extensive in the upper part. Lecithin was hydrolyzed to L-αlysolecithin and free fatty acids, which were absorbed in parallel in the upper small intestine. 3.5-6.5 g lecithin and 0.2-0.4 g cholesterol were delivered via the bile during passage of a test meal. Phospholipids partitioned in a glyceride bile salt mixture in favour of the bile salt micellar phase. © 1969 Informa UK Ltd.
