Detailed explanation-2: -Lipids are organic molecules composed of carbon, hydrogen, and oxygen atoms. The ratio of hydrogen atoms to oxygen atoms is much higher in lipids than in carbohydrates. Lipids include steroids (the material of which many hormones are composed), waxes, and fats.

Detailed explanation-3: -Carbohydrates are organic compounds such as sugars and starches. They provide energy and form structures such as cell walls. Lipids are organic compounds such as fats and oils. They store energy and help form cell membranes in addition to having other functions in organisms.
