An organic acid is an , -SH, Enol group, and the Phenol group. In biological systems organic compounds containing only these groups are not generally referred to as organic acids. CHARACTERISTICS Generally, organic acids are weak acids and do not dissociate completely, compared with strong Mineral Acid s. Lower molecular weight organic acids such as Formic and Acetic Acid s are miscible in water, but higher molecular weight organic acids such as Benzoic Acid are insoluble in molecular (neutral) form. On the other hand, most organic acids are very soluble in organic solvents. ''p''-Toluenesulfonic Acid is a comparatively strong acid used in organic chemistry often because it is able to dissolve in the organic reaction solvent. Exceptions to these solubility characteristics exist in the presence of other substituents which affect the polarity of the compound. APPLICATIONS Simple organic acids like formic or acetic acid are used for oil and gas cell stimulation treatments. These organic acids are much less reactive with metals than are strong mineral acids like HCl or mixtures of HCl and HF. For this reason, organic acids are used at high temperatures or when long contact times between acid and pipe are needed. The conjugate bases of organic acids such as Citrate and Acetate are often used in biologically-compatible Buffer Solution s. Biological systems create many and more complex organic acids such as L-lactic , Citric and D-glucuronic Acid s that contain Hydroxyl or Carboxyl Group s. Human blood and urine contain these plus organic acid degradation products of Amino Acids , Neurotransmitters and intestinal bacterial action on food components. Examples of these categories are alpha-ketoisocaproic, vanilmandelic and D-lactic acids, derived from Catabolism of L-leucine and Epinephrine (adrenaline) by human tissues and catabolism of dietary carbohydrate by intestinal bacteria, respectively.
