WebThis graph depicts the protonation state of glutamate as the pH changes. At a pH below the pKa for each functional group on the amino acid, the functional group is protonated. At a pH above the pKa for the functional group it is deprotonated. If the pH equals the pKa, the functional group is 50% protonated and 50% deprotonated. Attribution: Ivy ... WebIndicators that change color at pH 7 must have a pKa or pKb of their functional group that reacts with the water, hydrogen ion, or hydroxide at 7 as well. This is because a small change in pH near the endpoint will create the most sensitive change in the indicator molecule since the pKa is the same. ... A chart summarizing the most popular ... WebA functional group may participate in a variety of chemical reactions.
