Textbook Problem

Draw the zwitterion structure for each of the following amino acids.

  1. a. Leucine
  2. b. Isoleucine
  3. c. Cysteine
  4. d. Glycine

(a)

Interpretation Introduction

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.

Explanation

The side chain present in the amino acid, leucine is CH2CH(CH

(b)

Interpretation Introduction

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 Introduction

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 Introduction

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.
