Neet Biology Mcq On Lipids

Lipids are organic, non-polar molecules that are energy-rich. They are composed of carbon, hydrogen, and oxygen atoms and are insoluble in water, but soluble in nonpolar solvents since water is a polar molecule. These molecules can be synthesized in the liver and are commonly found in butter, whole milk, oil, cheese, fried foods, and certain red meats.
