Structure and Properties of Peptides The peptide bond in proteins is is planar because of steric hinderance usually trans unless proline is the next amino acid only found between proline residues usually cis unless proline is the next amino acid is planar because of steric hinderance usually trans unless proline is the next amino acid only found between proline residues usually cis unless proline is the next amino acid ANSWER DOWNLOAD EXAMIANS APP
Structure and Properties of Peptides The Ramachandran Plot illustrates the fact that the F & Y angles can assume any value in a peptide the F & Y angles can assume approximately three different values the peptide bond is planar the F & Y angles can assume only a single value in a protein the F & Y angles can assume any value in a peptide the F & Y angles can assume approximately three different values the peptide bond is planar the F & Y angles can assume only a single value in a protein ANSWER DOWNLOAD EXAMIANS APP
