WebIonic Groups Compounds that contain carboxyl groups are called acids (or carboxylic acids). As illustrated in Figure 1.1, a carboxyl group in aqueous solution is partially ionized to the carboxylate anion. The degree of ionization depends on the dissociation constant of the acid and the initial pH of the solution. Webthe carboxyl groups may be determined from the chem- ical shift (see equation); thus fatty acids such as oleic acid, at physiologic pH (pH 7.4), would be about half ionized if present in a phospholipid membrane or lipo- protein surface but would be completely ionized if bound to albumin.
