  1. How do the non-polar AA interact with each other?
    • The are hydrophobic so they agregate in the center with the R groups facing outwardly-
    • This is called hydrphobic effect

    Hydrogen bonding
  2. Name the nine non-polar amino acids.
    Which are the unique two and why?
    • Glycine
    • Alanine
    • Isoluecine
    • Luecine
    • Valine
    • Triptophan
    • Proline
    • Methionine

    Two weird ones are methionine and tryptophan bc they have electronegative atoms
  3. What are the primary functions of proteins? (6)
    • Structural
    • Signaling
    • Enzymatic catalysis
    • Transport
    • Gene regulation
    • Protection
  4. Name the uncharged polar amino acids.
    • Serine
    • Asparagine
    • Glutamine
    • Tyrosine
    • Threonine
    • Cysteine
  5. What kind of interactions do polar, uncharged amino acids have?
    Hydrogen bonding

    Disulfide bonds between cysteines only, but cysteines can also still hydrogen bond (hydrogen bonds are weaker than covalent disulfide bonds)
  6. What are the amino acids with charged polar R-groups?
    How do they interact?

    Hydrogen bonding
    Ionic bonds- negatively charged acids will bond with positively charged R groups
    • Glutamic acid -
    • Aspartic acid -
    • Arginine +
    • Lysine +
    • Histidine kind of neutral to semi positive
  7. What are the four structures of a protein. Explain each.
