draw a “trans” and a “cis” peptide bond of alanine and threonine with the peptide bond lying in the plane of the paper. Draw a second view of each peptide bonds now looking down/along the peptide bond (i.e. one atom of the peptide bond will be in front and will obscure the second one behind it). Using a circular arrow, demonstrate how the torsion angle can be directly “read” from the picture. You can do this with an accuracy of ~10°. Provide an explanatory caption.
