Oleic acid and cholesterol absorption by Caco-2 cell monolayers. ³H-oleic acid and ¹⁴C-cholesterol were added to lipid micelles and incubated for 24 h. Absorbed tracers were calculated as described in the “Materials and Methods” section. A and B, % of absorbed ³H-oleic acid and ¹⁴C-cholesterol, respectively. * p<0.05 and ** p<0.01 vs lipid micelles alone. Data are shown as means and SEM of triplicate assays. The concentrations of reagents added to lipid micelles were 0.2 mmol/l, respectively.
