For the dipeptide Phe-Phe, s-cis conformation needs to be drawn and the source of large steric interaction needs to be identified. Concept introduction: The peptide bonds are simply amide linkages. These amide linkages have a resonance structure where the C-N bond has got some double-bond character. Due to this there is a restricted rotation in the amide bond as we see in normal amides. This restricted rotation gives rise to two possible conformations known as s-trans and s-cis. Please remember that s-trans conformation is more stable than s-cis conformation due to less steric interactions. To draw and identify : the s-cis conformation for Phe-Phe and to identify the source of steric interactions
