Concept explainers
(a)
Interpretation: The classification of the given standard amino acid as hydrophobic or hydrophilic has to be stated.
Concept introduction: The amino acid that has one
The amino acid that has one amine group, one carboxyl group and a polar side chain is called polar amino acid. The polar amino acid is soluble in water. Thus, it is hydrophilic in nature.
(b)
Interpretation: The classification of the given standard amino acid as hydrophobic or hydrophilic has to be stated.
Concept introduction: The amino acid that has one amine group, one carboxyl group and nonpolar side chain is called non-polar amino acid. The non-polar amino acid is not soluble in water. Thus, it is hydrophobic in nature.
The amino acid that has one amine group, one carboxyl group and a polar side chain is called polar amino acid. The polar amino acid is soluble in water. Thus, it is hydrophilic in nature.
(c)
