[[File:Pimaric_acid_structure.svg\|thumb\|right\|Chemical structure of pimaric acid]]
			'''Pimaric acid''' is a naturally occurring [[resin acid]] found in the oleoresin of certain [[pine]] species. It is a member of the [[diterpene]] family of organic compounds, which are known for their complex structures and diverse biological activities.

			==Chemical structure==
			Pimaric acid is classified as a [[diterpene]] due to its structure, which is based on a 20-carbon skeleton derived from four [[isoprene]] units. The chemical formula of pimaric acid is C<sub>20</sub>H<sub>30</sub>O<sub>2</sub>. The structure of pimaric acid includes a carboxylic acid group, which contributes to its acidic properties.

	Pimaric acid is found in the ~~resin of various species~~ of pine trees, ~~including~~ the [[~~Scots pine~~]] ~~(Pinus sylvestris),~~ the [[~~loblolly~~ pine]] ~~(Pinus taeda)~~, ~~and the [[longleaf pine]] (Pinus palustris)~~. It is ~~also found in~~ the ~~bark of some species of conifer~~ trees~~, such as~~ the ~~[[Douglas fir]] (Pseudotsuga menziesii)~~.		Pimaric acid is primarily found in the [[oleoresin]] of pine trees, particularly those belonging to the [[Pinaceae]] family. It is one of the major components of [[pine resin]], which is harvested for various industrial applications. The resin is typically obtained by tapping the trees and collecting the exudate.

	==~~Uses~~==		==Applications==
	Pimaric acid is used in the production of [[~~rosin~~]], ~~a resinous substance used in a variety of industrial applications, including the manufacture of~~ [[~~varnish]], [[soap~~]], and [[~~paper~~]]. It is also ~~used~~ in the ~~production~~ of ~~[[turpentine]]~~, a ~~solvent used~~ in ~~the paint and varnish industry~~.		Pimaric acid and its derivatives have several applications in industry. They are used in the production of [[adhesives]], [[varnishes]], and [[inks]]. The acid is also utilized in the synthesis of other chemical compounds, serving as a precursor in various chemical reactions.

	==~~Health Effects~~==		==Biological activity==
	~~While~~ pimaric acid ~~is generally considered safe, it can cause skin irritation in some individuals~~. It ~~is not considered toxic~~, ~~but~~ it ~~can cause allergic reactions~~ in ~~individuals who are sensitive to it~~.		Research has shown that pimaric acid exhibits a range of biological activities. It has been studied for its potential [[antimicrobial]], [[anti-inflammatory]], and [[antioxidant]] properties. These activities make it a compound of interest in the development of new pharmaceuticals and natural health products.
