Fatty Acids A carbon-based molecule that can store large amounts of energy; building blocks of lipids.
Carbohydrates Biomolecules made of oxygen, hydrogen, & carbon that organisms use for structural support & energy storage; can be broken down into simple sugars.
Sugars (Glucose) A simple molecule with stored chemical energy; product of photosynthesis & building blocks of the carbohydrates in our bodies & in the food we eat.
Fiber Tough, stringy structures in plants that the human body cannot digest or break down, making them pass unchanged through the digestive system.
