It is a derivative of trans-[[cinnamic acid]]. As a component of lignin, ferulic acid is a [[wiktionary:Precursor|precursor]] in the manufacture of other [[aromatic]] compounds. Etymology : from Ferula, giant fennel. ==Occurrence in nature== Ferulic acid, together with dihydroferulic acid, is a component of lignocellulose, serving to crosslink the lignin and polysaccharides, thereby conferring rigidity to the cell walls.<ref>Iiyama, K.; Lam, T B.-L.; Stone, B. A. "Covalent Cross-Links in the Cell Wall" Plant Physiology, 1994 volume 104, pp. 315-320.</ref> It is found in seeds of plants such as in [[rice]], [[wheat]], and [[oats]], as well as in [[coffee]], [[apple]], [[artichoke]], [[peanut]], [[orange (fruit)|orange]] and [[pineapple]]. It can be extracted from wheat bran and maize bran using concentrated alkali. [[Biosynthesis]] of ferulic acid is by the action of the enzyme O-methyl transferase on [[caffeic acid]] {{ref_label|1|1|a}}. It is an intermediate in the synthesis of monolignols, i.e., the monomers of [[lignin]], and is also used for the synthesis of [[lignans]]. ==Bio-medical considerations== Ferulic acid, like many [[phenol]]s, is an [[antioxidant]] in the sense that it is reactive toward [[free radical]]s such as [[reactive oxygen species]] (ROS). ROS and free radicals are implicated in [[DNA repair#DNA damage|DNA damage]], [[cancer]], accelerated cell [[senescence|aging]]. Animal studies and [[in vitro]] studies suggest that ferulic acid may have direct antitumor activity against [[breast cancer]] {{ref_label|2|2|a}} and [[Hepatocellular carcinoma|liver cancer]] {{ref_label|3|3|a}}. Ferulic acid may have pro-[[apoptosis|apoptotic]] effects in cancer cells, thereby leading to their destruction {{ref_label|3|3|b}}. Ferulic acid may be effective at preventing cancer induced by exposure to the carcinogenic compounds [[benzopyrene]] {{ref_label|4|4|a}} and [[4-nitroquinoline 1-oxide]] {{ref_label|5|5|a}}. Note that these are not [[randomized controlled trial]]s done with human participants, and therefore, the results of these studies may not be directly applicable to human use. If added to a topical preparation of [[ascorbic acid]] and [[vitamin E]], ferulic acid may reduce [[oxidative stress]] and formation of [[thymine dimer]]s in [[skin]] {{ref_label|6|6|a}}. ==Applications== ===As a precursor to vanillin=== Ferulic acid, being highly abundant, may be useful as a precursor in the manufacturing of [[vanillin]], a synthetic [[flavoring]] agent often used in place of natural [[vanilla]] extract {{ref_label|7|7|a}}. However, biotechnological processes may be the most efficient method to use ferulic acid as a precursor {{ref_label|8|8|a}}, and as such, research is still ongoing. ===Mass spectrometry=== It is used as a matrix for [[protein]]s in [[Matrix-assisted laser desorption/ionization|MALDI]] [[mass spectroscopy]] analyses. {{ref_label|9|9|a}} ==See also== * [[Caffeic acid]] * [[Coumaric acid]] * [[Diferulic acids]] * [[Sodium ferulate]], a ferulic acid salt ==References== {{reflist}} # {{note_label|1|1|a}} {{cite book |author= Shahadi, Fereidoon|coauthors= Naczk, Marian|title= Phenolics in food and nutraceuticals| origyear= 2004|publisher= CRC Press LLC|location= Florida, USA|isbn= 1-58716-138-9|pages= pp. 4|}} # {{note_label|2|2|a}} [[Image:Free text.png]] Antiproliferative and apoptotic effects of selective phenolic acids on T47D human breast cancer cells: potential mechanisms of action.
