Concept explainers
(a)
Interpretation: The zwitter ion structure of leucine has to be drawn.
Concept introduction: In the zwitter ion form of amino acids, the amino group is protonated and thus has a positive charge. However, the carboxyl group losses a proton and has a negative charge.
(b)
Interpretation: The zwitter ion structure of isoleucine has to be drawn.
Concept introduction: In the zwitter ion form of amino acids, the amino group is protonated and thus has a positive charge. However, the carboxyl group losses a proton and has a negative charge.
(c)
Interpretation: The zwitter ion structure of cysteine has to be drawn.
Concept introduction: In the zwitter ion form of amino acids, the amino group is protonated and thus has a positive charge. However, the carboxyl group losses a proton and has a negative charge.
(d)
Interpretation: The zwitter ion structure of cysteine has to be drawn.
Concept introduction: In the zwitter ion form of amino acids, the amino group is protonated and thus has a positive charge. However, the carboxyl group losses a proton and has a negative charge.
