Question

Quizplus · Accepted Answer

An ionizable center is a functional group on a drug molecule that can donate or receive protons (H+), resulting in the formation of a charged species called an ion. These ionizable centers can be acid groups (such as carboxylic acids) or basic groups (such as amines). The ability of an ionizable center to donate or receive protons is characterized by its pKa, which is the pH at which the ionizable center is 50% protonated and 50% deprotonated. Therefore, option B is the best choice as the other options are either incorrect or incomplete.
