The Site of Absorption of Cholesterol and Sitosterol in the Rat Small Intestine

Abstract

Sylvén, C. & Nordstrom, C. 1970. The Site of Absorption of Cholesterol and Sitosterol in the Rat Small Intestine. Scand. J. Gastroent. 5, 57-63.

Cholesterol-4-¹⁴C and sitosterol-22,23-³H in micellar solution or dissolved in triolein were administered to rats. Sterols were uniformly taken up by the proximal (micellar solution) or by the middle part (triolein solution) of the small intestine. The apical halves of the villi contained the major amount of sterols taken up. The two sterols had identical areas of uptake.

Key-words:

• Cholesterol
• intestinal absorption
• localization
• micellar solution
• rat
• sitosterol
• triolein
