    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.
