Question

QUESTION 1 Which the following bonds in peptide backbones is the least mobile O Phi (N-Calpha) O Psi (Calpha -CO) O omega (CO-N) Calpha -Cbeta O All have similar constraints QUESTION 2 Which protein secondary structure has local contacts between residues within 3-4 amino acids on the same polypeptide chain. O alpha helix o beta sheet beta turn O A and C All of the above QUESTION 3 A ramachandran plot of phi and psi angles for each residue in a protein is a useful tool to determine O The association state of a protein The isoelectric point of a protein O The quality of a protein structure The stability of a protein None of the above

Explanation / Answer

ANSWER 1
The omega bond is the least mobile one because of partial double bond character restricting all constituent atoms into a plane.

ANSWER 2
A. Alpha Helix & C. Beta Turn have local contacts between residues 3-4 amino acids away

ANSWER 3
Ramachandran plot can help us figure out the quality of a protein structure by offering permissible regions of Phi and Psi bonds.
