Study Notes
Lipid Characteristics
- Lipids are hydrophobic due to their non-polar nature, resulting in low solubility in water.
Triglycerides
- The main function of triglycerides in the body is to store energy.
- Triglycerides are the main component of fats and oils.
Cholesterol
- Cholesterol is a precursor of many steroid hormones and Vitamin D.
Lipid Solubility
- Lipids are soluble in non-polar solvents, such as chloroform and ether.
Dietary Role
- The main role of lipids as dietary constituents is to provide energy.
Fat-Soluble Vitamins
- Lipids are carriers of fat-soluble vitamins, including Vitamins A, D, E, and K.
