Question

Which of the following interactions are generally considered to be unfavorable? Group of answer choices a)Interaction between Lys and Glu at neutral pH, assuming standard pKa values of Lys and Glu. b)Interaction between a backbone amino group and a side chain carbonyl group. c)Interaction between two alpha helices. d)Interaction between Arg and Lys side chains at a pH of 7, assuming standard pKa values for Arg and Lys.

Answer 1

d) Interaction between Arg and Lys side chains at a pH of 7, assuming standard pKa values for Arg and Lys.

Step-by-step explanation:

Arginine and Lysine are basic amino acids. They play same role in various membrane proteins. They both have high aqueous values which give rise to high electrostatic interaction. The interaction is mainly in the cations of the side chains. They both are heterologous secreted proteins which plays role of metabolite.
