Identify a similarity between carbohydrates and lipids

Carbohydrates and lipids are both macronutrients and provide several key functions to the human body.

Explanation:

These nutrients have similar chemical structures and the body uses carbohydrates and lipids in similar ways. Carbohydrates are molecules composed of carbon, hydrogen and oxygen, with a ratio of one atom of carbon and two atoms of hydrogen for every atom of oxygen. Lipids have the same elements as carbohydrates, but differ in their linkage.
