Chapter 10: Q10FE (page 230)

Draw the structures of the predominant forms of glutamic acid and tyrosine at $pH 9.0$ and $pH 10.0$ What is the second most abundant species at each ?.

Short Answer

Expert verified

The Predominant form, Secondary form of given pH drawn.

Step by step solution

Step 1: Define the term predominant form

The term "predominant form" refers to the most stable form of matching molecules in a compound with the least amount of energy.

Draw the glutamic form acid.

It has two acid functional groups and one amine functional group.

When the pH is 9.00, the amine protonated form is prevalent, and this form is the most stable, but when the pH is raised to 10.00,

The amine is free and acid deprotonated

Draw the Tyrosine form acid.

At pH 10 and 9, the acid deprotonated form predominates.

Tyrosine is virtually neutral in this secondary form, with one positive and one negative, but free amine, acid, and phenol are deprotonated at pH 10.00.
