E)All have equal stability.

Question

Quizplus · Accepted Answer

Beta sheets, especially those composed of hydrophobic amino acids like Valine (Val), Isoleucine (Ile), and Phenylalanine (Phe), tend to form stable structures due to hydrophobic interactions. These interactions help in stabilizing the protein structure by keeping these non-polar side chains away from the aqueous environment, thus contributing to the overall stability of the protein.
