The effects of oleic and elaidic acid upon the in vitro intestinal upt
ake of cholesterol were studied in 9 weeks-old male and female rats. E
laidic acid increases the uptake of cholesterol when compared to oleic
acid in both males and females. It is suggested that elaidic acid may
enhance the esterification of cholesterol within the enterocyte throu
gh being more available for esterification and/or through being prefer
entially incorporated into cholesterol esters.
