Study Notes
Lipid Absorption and Function
- Bile salts are the major emulsifying agent for the digestion and absorption of fats.
Energy Source and Cell Membranes
- Dietary lipids provide between 30% and 45% of average energy intake.
- Phospholipids are a major constituent of cell membranes.
Lipid Classification
- Cholesterol is a metabolically important lipid but is not a significant source of metabolic fuel.
Vitamin Absorption
- Vitamin A, vitamin D, vitamin E, and vitamin K are absorbed in the body in a lipid-soluble form.
Fats and Oils
- The main difference between oils and fats is their physical state at room temperature, with oils being liquid and fats being solid.
