Skills to Develop
- describe the differences between primary, secondary, supersecondary, tertiary, quaternary and domain protein structure
- explain the basis of CD measurements for secondary structure
- describe the similarities between torsion angles and an energy vs torsion angle plot for the rotation of the C2-C3 torison angle with phi/psi angles of peptide bonds and the 2D plots off allowed conformations around a given amino acid in a protein (Ramachandran plot).
- (from reading give explanation for observed propensities of amino acids for different secondary structure)
