Alanine, arginine, glutamine, and histidine are all amino acids, but they are classified differently based on their side chains.
- Acidic: Histidine
- Basic: Arginine
- Neutral Polar: Glutamine
- Neutral Nonpolar: Alanine
Classification of Amino Acids Based on Their Side Chains
- Alanine is classified as a neutral nonpolar amino acid because it has a nonpolar side chain.
- Arginine is classified as basic because it has a positively charged side chain.
- Glutamine is classified as a neutral polar amino acid because it has an amide side chain.
- Histidine is classified as acidic because it has an acidic side chain that can be protonated.
Thus, alanine is neutral nonpolar, arginine is basic, glutamine is neutral polar, and histidine is acidic.
