Following a meal, the stomach and upper gastrointestinal contents consist of

• food compounds
• complex lipids/micellar/aqueous/hydrocolloid and hydrophobic phases
• hydrophilic phases
• solid, liquid, colloidal and gas bubble phases.

Micelles are colloid-sized clusters of molecules which form in conditions as those above, similar to the critical micelle concentration of detergents. In the upper gastrointestinal tract, these compounds consist of bile acids and di- and monoacyl glycerols which solubilize triacylglycerols and cholesterol.
