What are phospholipids?

Lipid compounds that attract both water- and fat-soluble substances
Proteins that carry oxygen in the blood
Sugars that provide energy to cells
Compounds that detoxify free radicals

The correct answer is: Lipid compounds that attract both water- and fat-soluble substances

Phospholipids are major components of cell membranes and function to separate the internal cellular environment from the external environment. Option B is incorrect because proteins do not attract both water- and fat-soluble substances. Option C is incorrect because sugars are not lipid compounds. Option D is incorrect because phospholipids do not detoxify free radicals; this function is typically carried out by antioxidants.
