Lipids - Fatty acids + Glycerol

• Lipids are made up of fatty acids and glycerol
• Lipids ( fats and oils ) are made from glycerol and three fatty acids.
• Unlike carbohydrates and proteins, lipids are NOT polymers because they don't form a long chain of repeating units
• Lipids contain carbon, hydrogen and oxygen atoms
• In the body, lipids are broken down by enzymes in the small intestine
• When lipids are broken down, the fatty acids will make the solution they are in more acidic ( it will have a lower pH )
