a)If you have 14 amino acids in a polypeptide chain, how many peptide bonds are there in the polypeptide chain?

b) T/F R groups affect peptide bond formation.

c)What is unique about the peptide bond and how does this characteristic affect the length of the bond?

d)What are the 3 Greek torsion angles and between what atoms are they located?

e)What is the dominant peptide bond conformation and why is this so? What amino acid exhibits the other conformation?

e)If you have 10 different amino acids and want to make a polypeptide chain of 6 amino acids, how many theoretical combinations of amino acids could you make?

f)If the molecular weight of a protein is 2000 Da, how many amino acids are in the protein?
