Biological molecules

• What are carbohydrates made of?

  Carbon, oxygen and hydrogen
• Difference between simple sugars and complex carbohydrates

  Large molecules made up of lots of individual smaller molecules called simple sugars

  Complex carbohydrates are polymers, while simple sugars are monomers
• 2 examples of complex carbohydrates

  Glycogen

  Starch
• Where are the carbohydrates broken down in the body

  Mouth

  Small intestines
• Protein (in terms of monomers and polymers)

  Made up of long chains of amino acids bonded together. A protein is a polymer and the amino acids it is made from are the monomers
• What are proteins made from?

  Carbon, hydrogen, oxygen and nitrogen
• Where are proteins broken down in the body

  Stomach

  Small intestines
• Structure of a lipid

  Contain a single glycerol molecule attached to three fatty acid molecules
• What are lipids made from

  Carbon, oxygen and hydrogen
• Are lipids polymers

  No because they aren’t formed from long chains of monomers
• Where are lipids broken down

  Small intestines
