Leucine - Polar negatively charged $R$ group

Vedclass · Answer

(D) Amino acids are classified based on the nature of their $R$ group.$1$. Phenylalanine has a benzyl side chain,which is hydrophobic and non-polar.$2$. Lysine has an amino group in its side chain,making it polar and positively charged at physiological $pH$.$3$. Glycine has a hydrogen atom as its $R$ group. It is considered non-polar because the $H$ atom does not contribute to polarity. Therefore,labeling it as 'polar uncharged' is incorrect.$4$. Leucine has an isobutyl side chain,which is hydrophobic and non-polar. Labeling it as 'polar negatively charged' is also incorrect.However,in the context of standard multiple-choice questions where one must identify the most glaring mismatch,Leucine is clearly non-polar and hydrophobic,not negatively charged. Glycine is the simplest amino acid and is non-polar. Given the options,$D$ is the most significant mismatch as Leucine is strictly non-polar.
