🤓 Based on our data, we think this question is relevant for Professor Owens' class at UCSD.
In an α helix, the position of an amino acid residue relative to its neighbors is important. The interactions in these neighboring amino acid side chains have a significant effect on the stability of α helical structures.
An α helix would be destabilized most by:
A. interactions between neighboring Asp and Arg residues
B. the presence of an Arg residue near the carboxyl terminus of the α helix
C. the presence of two Lys residues near the amino terminus of the α helix
