-Amine group
-Carboxylic acid
-Hydrogen
-R group
2
Q
Peptide bond
A
Bond between two amino acids
3
Q
L and S configurations (vs. D and R)
A
Configuration of all natural amino acids
4
Q
Molecular weight of an amino acid
A
110 amu
5
Q
Glycine (why it is unique)
A
Only achiral amino acid; can’t rotate plane polarized light
6
Q
Cysteine (why it is unique)
A
Engages in both H-bonding and disulfide bonds to form disulfide bridges
7
Q
Proline (why it is unique)
A
Side chain is bound to the amine group, forming kinks in the chain that are important for secondary structure
