Citric Acid: A Multifunctional Pharmaceutical Excipient
Citric acid is a weak tricarboxylic acid found in citrus fruits like lemons, which contain 7–9% citric acid according to their dry weight. The three carboxylate groups of citric acid monohydrate have different pKa values, namely 3.15, 4.78, and 6.40 [ 7 ]. Until 1919, lemons were the main source of citric acid ( Figure 1 ).
