Module 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
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
What are the primary functions of proteins? (6)
- Structural
- Signaling
- Enzymatic catalysis
- Transport
- Gene regulation
- Protection
Name the uncharged polar amino acids.
- Serine
- Asparagine
- Glutamine
- Tyrosine
- Threonine
- Cysteine
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)
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
What are the four structures of a protein. Explain each.
