Ferulic acid is a plant chemical that acts as an antioxidant and is found in various plant species. It is synthesized by an enzyme called o-methyl transferase and is often used in supplements claiming to slow down aging. It is also used in the production of an artificial form of vanilla flavor and in the study of protein molecules.
Ferulic acid is a naturally occurring chemical found in the cell walls of plants. It is one of several naturally occurring plant chemicals, called phytochemicals, found in a wide variety of plant species. The official name of this chemical is 4-hydroxy-3-methoxycinnamic acid and its molecular formula is C10H10O4. The chemical is synthesized within plant cells by an enzyme called o-methyl transferase, which uses caffeic acid, a phytochemical that despite its name is not related to caffeine, to produce ferulic acid.
The structure of ferulic acid is based on a benzene ring and, like many phytochemicals, it acts as an antioxidant by absorbing free radicals from the surrounding environment. As an antioxidant it can, therefore, act as an anticancer agent. It is often used as an ingredient in various supplements that claim to slow down the aging process. Such supplements sometimes go by the name of ferulic acid serum. Other health benefits that have been attributed to this substance include lowering blood cholesterol, protecting against bone degeneration, stabilizing blood glucose levels in diabetic patients, and relieving the symptoms of “hot flashes” experienced. by menopausal women.
In its native form in plant cell walls, ferulic acid works in conjunction with another phytochemical called dihydroferulic acid to form part of a compound called lignocellulose, an important structural substance in plant cells that provides cell wall strength. This substance is particularly common in the seeds and leaves of cereal plants, including wheat, rice, corn and oats. Other sources include fruits such as pineapples, apples and oranges.
The solubility of ferulic acid is based on an alkaline environment, and the chemical can be extracted from various plants with the use of a strong alkali solution. Ferulic acid esterase, an enzyme that can be picked up by some bacteria and fungi, is sometimes used to aid in the extraction process. Once extracted and purified, the substance takes the form of a yellow powder.
Uses for this chemical, in addition to applications in health and alternative medicine, include the production of an artificial form of vanilla flavor. It is also sometimes used by scientists when they study the structure of some protein molecules by mass spectrometry. A solution of ferulic acid can be used to suspend protein molecules, whose structure can then be analyzed using laser technology.
