Organic anion
Encyclopedia
Organic anions are chemically heterogeneous substances possessing a carbon backbone and a net negative charge. Organic anions are conjugate bases of organic acid
s. The following table lists some of the organic anions and their conjugate acids which are substrates of the organic acid transporter (OAT) family of transmembrane proteins.
Organic acid
An organic acid is an organic compound with acidic properties. The most common organic acids are the carboxylic acids, whose acidity is associated with their carboxyl group –COOH. Sulfonic acids, containing the group –SO2OH, are relatively stronger acids. The relative stability of the conjugate...
