What is the difference between lipids and carbs?

• Carbohydrates provide cells with the structures to build & repair cells, while lipids code for the cell's genetic info.

• Carbohydrates supply cells with fast, easy to use energy, while lipids supply cells with more, long-term energy.

• Lipids supply cells with fast, easy to use energy, while carbohydrates supply cells with more, long-term energy.
