  2. What other elements can protein sometimes contain?
    Sulfur (S) and phosphorus (P)
  3. What sub-units are proteins made up of?
    Amino acids
  4. How many different types of amino acids are there?
  5. What kind of bonds hold amino acids together?
    Peptide bonds
  6. What are the long chains amino acids are joined together by called?
    Polypeptide chains
  7. What determines the structure and function of the protein?
    The sequence of amino acids
  8. What are the two types of proteins? (in their tertiary structure)
    Fibrous or globular
  9. Describe fibrous proteins and give an example
    • Fibrous proteins are structural proteins
    • They are made up of long parallel polypeptide chains
    • They have contractile properties
    • Examples include keratin in your hair, collagen in bone and tendons, actin and myosin in muscle
  10. Describe globular proteins and give an example
    • Globular proteins are more of a sphere shape
    • They are enzymes, some hormones, structural proteins and antibodies
