Which of the following defines a zwitterion? (More than one answer may be correct.) A zwitterion is a molecule that is neutral, with a full positive charge and a full negative charge on different atoms. O A zwitterion is a molecule that is charged, with a full positive charge and a full negative charge on different atoms. O A zwitterion is a molecule that has a partial positive charge and a partial negative charge on different atoms. O A zwitterion...
Predict the product(s) for the following reaction: NaNH2. NH3 NH2 NH2 NH2 =
The structure of alanine is shown at the right in its fully protonated form. The pK_a for the ionizable groups are 2.3 (alpha-carboxyl group), and 9.7 (alpha-amino group). Calculate the pH at which alanine will have a net charge of 0. pH = Select the true statements about alanine when the pH is equal to its pl. If an electric field is applied, alanine will not move toward either electrode. Since alanine does not have an ionizable R group, the...
