Question 5 1 pts Which of the following statements is/are true concerning peptide bonds? They are the only covalent bond formed between amino acids in polypeptide structures. The angles between the participating C and N atoms are described by the values psi (?) and phi (?). They have partial double-bond character. All of the above are true. Question 6 1 pts In an ? helix, the R groups on the amino acid residues are found on the outside of the helix spiral. participate in the hydrogen bonds that stabilize the helix. allow only right-handed helices to form. A and B are true.

Step 1
- This statement is true. Peptide bonds are the covalent bonds that link amino acids together in a polypeptide chain. Statement 2: The angles between the participating atoms are described by the values psi (ψ) and phi (φ). - This statement is true. The angles ψ Show more…

The angles between the participating C and N atoms are described by the values psi (ψ) and phi (ϕ). They have partial double-bond character. All of the above are true. Question 6 In an α helix, the R groups on the amino acid residues are found on the outside of the helix spiral. participate in the hydrogen bonds that stabilize the helix. allow only right-handed helices to form. A and B are true.
