![]() ![]() ![]() So yeah, we were left the remaining but not this. Protein secondary structure Page: 122 Difficulty: 1 Ans: D A D-amino acid would. The backbone chain bonds on either side of the alpha carbon (designated by phi and psi) can freely rotate. In the case of peptides, this parameter is called the torsional angle. So yeah, there will be double born and yet there will be a connection of nitrogen in this way. Rotatible and non-rotatible bonds in a polypeptide. Which pairs of bonds within a peptide backbone show free rotation around both bonds AN-C and GC N-Ca and NC c. Rotation around single bonds in alkanes is described in terms of a dihedral angle. So here double one oxygen can be present and discipline to show hydrogen bonding in this fashion here, there will be hydrogen and to this then when we oxygen connection here there will be oxygen connection over here via hydrogen bonding in this fashion. This is a result of the partial double bond character of the peptide bond which is caused by resonance effects, i.e. So here what can happen is and it is present. The amine group in the polypeptide cannot. Then we have this again nitrogen then hydrogen which is present to this where we have a hydrogen present in this fashion and this thing. Due to the double bond between the amine group and the carboxyl group, no rotation is possible around that bond. So basically if you see the structure for this year, we will have nitrogen then there is a double bond oxygen over here. The other is the: A) formation of the maximum number of hydrophilic interactions. Even though the C-N looks like it should be a single bond allowing for free rotation, resonance interactions in amides make the C-N bond act more like a double. ![]() So this pair of the bond within the peptide backbone show free rotation at all both boards. So the correct answer for this is the last part that is see alpha. One is the formation of the maximum number of hydrogen bonds. So in this question we have been asked in the following years of bond with within a peptide backbone show free rotation around both boards. But I can say that hydrogen bonding do that. Study with Quizlet and memorize flashcards containing terms like In an aqueous solution, protein conformation is determined by two major factors. The hydrogen bonding to the Almighty baboon group is going to happen in this swamp. ![]()
