<p>CSV import</p> <p><b>New page</b></p><div>&#039;&#039;&#039;Organic acid&#039;&#039;&#039;<br /> <br /> An &#039;&#039;&#039;organic acid&#039;&#039;&#039; 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 [[ester]] group, and the [[amide]] group. In biological systems, organic compounds containing these groups are generally referred to as organic acids.<br /> <br /> == Classification ==<br /> <br /> Organic acids are classified into [[aliphatic acids]], [[aromatic acids]], [[alicyclic acids]], and [[heterocyclic acids]].<br /> <br /> == Properties ==<br /> <br /> Organic acids are usually weak, meaning that they do not fully [[dissociation|dissociate]] into their ions in water. Lower molecular mass organic acids such as [[formic acid]] and [[lactic acid]] are miscible in water and are quite polar, meaning they tend to be soluble in water. Higher molecular mass organic acids, such as [[benzoic acid]], are much less soluble due to the larger nonpolar aliphatic region.<br /> <br /> == Applications ==<br /> <br /> Organic acids are used in food preservation because of their effects on bacteria. The key advantage of using organic acids such as [[fumaric acid]], [[acetic acid]], and [[lactic acid]] is that they maintain the fresh flavor of the food product while providing increased shelf life.<br /> <br /> == See also ==<br /> * [[List of carboxylic acids]]<br /> * [[Acid strength]]<br /> * [[Acid dissociation constant]]<br /> * [[Acid-base reaction theories]]<br /> <br /> [[Category:Organic acids]]<br /> [[Category:Acids]]<br /> [[Category:Organic compounds]]<br /> <br /> {{stub}}<br /> {{dictionary-stub1}}</div>
