Fats are a sub-group of compounds known as lipids that are found in the body and have the general property of being hydrophobic (meaning they are insoluble in water). Fats are also known as triglycerides, molecules made from the combination of one molecule of glycerol with three fatty acids, as depicted at the right:
Carbohydrates are the body’s main energy source and are found inside ALL different cell types. Below are EXAMPLES of 1) a monosaccharide, 2) a polysaccharide, and 3) structures that are used to store carbohydrates in plants. Monomer Polymer Cellular context

Explain why carbohydrates and lipids are used preferentially to proteins as an energy source Differentiate between saturated and unsaturated fatty acids Lipids
3.4 What Are the Chemical Structures and Functions of Lipids? • Fats and oils store energy • Phospholipids—structural role in cell membranes • Carotenoids and chlorophylls—capture light energy in plants (photoreceptor) • Steroids and modified fatty acids—hormones and vitamins • Animal fat—thermal insulation
The document is a worksheet about carbohydrates that contains 19 multiple choice and fill-in-the-blank questions. It asks students to identify the basic components of carbohydrates like monosaccharides, disaccharides, and polysaccharides.
1- Compare the molecular formula of a carbohydrate with that of carbon dioxide. What does the presence of hydrogen atoms in carbohydrates indicate? A. Carbohydrates are more oxidized than carbon dioxide, and are therefore higher in potential energy. B. Carbohydrates are more reduced than carbon dioxide, and are therefore higher in potential energy.
