Concept explainers
(a)
Interpretation:
Whether the side chain of glycine is polar, nonpolar, basic, or acidic has to be determined.
Concept Introduction:
Amino acids are the
On the basis of these side chains, amino acid can be divided into two categories, polar and nonpolar. In nonpolar amino acids, side chains are nonpolar and in polar amino acid, side chains are polar.
On the bases of charge present on the side chain at
1. Polar neutral amino acids
2. Negatively charged amino acids. They are acidic amino acids.
3. Positively charged amino acids. They are basic amino acids.
(b)
Interpretation:
Whether the side chain of proline is polar, nonpolar, basic, or acidic has to be determined.
Concept Introduction:
