Consider the equilibrium shown below. When one looks at the equilibrium where X = CH₃ and the one where X = CH(CH₃)₂, how do the values of the equilibrium constants (Ks) compare? A) The Ks are equal. B) The K where X = CH₃ is greater. C) The K where X = CH(CH₃)₂ is greater. D) The Ks differ only slightly and are both less than 1.

The addition of the CH group to the peptide sequence increases the complexity of the molecule, making it less likely to dissociate into its constituent parts, which would decrease the value of the equilibrium constant. Therefore, the equilibrium where X = CH(CH₃)₂, which has the additional CH group, will have a higher K value compared to where X = CH₃.
