Lipids

Carbon chains are principal features of both carbohydrates and lipids.  What is the primary difference between these two types of macromolecules?

• Lipids always have longer carbon chains than carbohydrates.
• Carbohydrates cannot form rings like lipids can.
• Lipids provide energy, but carbohydrates cannot.
