Alanine

Vedclass · Answer

(A) Amino acids are classified based on the nature of their $R$ group. $1$. Alanine has a methyl group $(-CH_3)$ as its $R$ group,which is non-polar and hydrophobic. $2$. Arginine has a positively charged,basic $R$ group. $3$. Glycine has a hydrogen atom $(-H)$ as its $R$ group,which is technically non-polar,but Alanine is the classic example of a non-polar amino acid with a hydrocarbon side chain. $4$. Tyrosine has a phenolic hydroxyl group,making it polar. Therefore,Alanine is the most appropriate answer for a standard non-polar $R$ group.
