Vedclass · Answer

(B) Amino acids are classified based on the nature of their '$R$' group. Non-polar amino acids have hydrophobic '$R$' groups that do not interact with water. Among the given options: $1$. Tyrosine contains a phenolic hydroxyl group,making it polar. $2$. Tryptophan contains an indole ring; while it has a nitrogen atom,it is generally classified as non-polar due to the large hydrophobic aromatic structure. $3$. Histidine contains an imidazole ring and is basic/polar. $4$. Threonine contains a hydroxyl group,making it polar. Therefore,Tryptophan is the correct answer as it is the most non-polar among the choices provided.
