Organic Acids

Group of organic compounds containing the carboxylic group -C(O)OH, formed by the oxidation of aldehydes. Acids such as formic, acetic, and pyruvic acids are often found in air masses containing the oxidation products of organic matter. Other multifunctional acids such as oxalic and malonic acid are often found in liquid droplets. The mechanism of their formation is not fully understood at the momentChemicals found in blood and urine that in increased amounts may indicate an enzyme deficiency. Disorders termed organic acidurias are characterized by episodes of vomiting, lethargy, and ketosis (an increase in certain kinds of chemicals, namely ketones). These conditions can be present with striking odors of urine, such as isovalericacidemia, in which an odor resembling that of sweaty socks occurs. Treatment can include a low-protein diet, sometimes supplemented with carnitine. An organic acid is an organic compound that is an acid. The most common example are the carboxylic acids whose acidity derives from a carboxyl group -COOH. Other groups can also cause a weak acidity: hydroxyl group -OH, -SH, enol group, -OSO3H, phenol group. Each organic acid is formed by a an oxygen atom forming a double covalent bond with one -OH group. This carbon attaches to an oxygen and one other carbon. When organic acids are reacted with alcohols, they form esters.
