Chapter 2.8, Problem 38WDYL
Summary Introduction
To understand: Why the amino acid leucine is classified as a non-polar amino acid.
Introduction:
The non-polar molecules are hydrophobic, and the polar molecules are hydrophilic in nature. The polarity is also influenced by the presence and number of alkyl groups. The amino acid will be more non-polar if there are more alkyl groups present. . Leucine is a non-polar aliphatic amino acid.
