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. Alcohols, with –OH, can act as acids but they are usually very weak. The relative stability of the conjugate base of the acid determines its acidity. Other groups can also confer acidity, usually weakly: the thiol group –SH, the enol group, and the phenol group. In biological systems, organic compounds containing these groups are generally referred to as organic acids.
A few common examples include:
- Lactic acid
- Acetic acid
- Formic acid
- Citric acid
- Oxalic acid
- Uric acid

Famous quotes containing the word organic:
“A special feature of the structure of our book is the monstrous but perfectly organic part that eavesdropping plays in it.”
