<p>CSV import</p> <p><b>New page</b></p><div>&#039;&#039;&#039;Caffeic acid&#039;&#039;&#039; is a type of [[organic compound]] that is classified as a [[hydroxycinnamic acid]]. It is a naturally occurring [[phenol]] that is found in a variety of plant species. Caffeic acid is a key intermediate in the biosynthesis of [[lignin]], which is a type of complex organic polymer that provides structural support in plants.<br /> <br /> == Structure and properties ==<br /> Caffeic acid is a crystalline compound that is slightly soluble in water. It has a molecular formula of C9H8O4 and a molecular weight of 180.16 g/mol. The compound has a melting point of 223-225 °C and a boiling point of 365.1 °C at 760 mmHg. The structure of caffeic acid consists of a [[benzene ring]] with a [[carboxylic acid]] group and a [[hydroxyl]] group attached to it.<br /> <br /> == Biosynthesis ==<br /> Caffeic acid is biosynthesized in plants through the [[phenylpropanoid pathway]]. This pathway involves the conversion of [[phenylalanine]] into [[cinnamic acid]] by the enzyme [[phenylalanine ammonia lyase]]. Cinnamic acid is then hydroxylated by [[cinnamate 4-hydroxylase]] to form [[p-coumaric acid]], which is further hydroxylated by [[coumarate 3-hydroxylase]] to produce caffeic acid.<br /> <br /> == Biological activity ==<br /> Caffeic acid has been found to exhibit a variety of biological activities. It has [[antioxidant]] properties and can scavenge [[free radicals]], thereby protecting cells from oxidative damage. Caffeic acid also has [[anti-inflammatory]] effects and can inhibit the production of [[pro-inflammatory cytokines]]. In addition, it has been shown to have [[antimicrobial]] activity against a range of bacteria and fungi.<br /> <br /> == Health effects ==<br /> Several studies have suggested that caffeic acid may have potential health benefits. It has been found to have [[anticancer]] properties and can inhibit the growth of various types of cancer cells. Caffeic acid may also have [[cardioprotective]] effects and can protect against heart disease. However, more research is needed to fully understand the health effects of caffeic acid.<br /> <br /> == See also ==<br /> * [[Hydroxycinnamic acids]]<br /> * [[Phenolic compounds in wine]]<br /> * [[Phenylpropanoid pathway]]<br /> <br /> [[Category:Phenols]]<br /> [[Category:Hydroxycinnamic acids]]<br /> [[Category:Antioxidants]]<br /> [[Category:Anti-inflammatory agents]]<br /> [[Category:Antimicrobial substances]]<br /> <br /> {{stub}}</div>
