Phenolic acids or phenolcarboxylic acids are phenolic compounds and types of aromatic acid compounds. Included in that class are substances containing a phenolic ring and an organic carboxylic acid function (C6-C1 skeleton). Two important naturally occurring types of phenolic acids are hydroxybenzoic acids and hydroxycinnamic acids, which are ...
Phenol (also known as carbolic acid, phenolic acid, or benzenol) is an aromatic organic compound with the molecular formula C 6 H 5 OH. [5] It is a white crystalline solid that is volatile. The molecule consists of a phenyl group (−C 6 H 5) bonded to a hydroxy group (−OH). Mildly acidic, it requires careful handling because it can cause ...
The simplest is phenol, C 6 H 5 OH. Phenolic compounds are classified as simple phenols or polyphenols based on the number of phenol units in the molecule. Phenol – the simplest of the phenols Chemical structure of salicylic acid, the active metabolite of aspirin. Phenols are both synthesized industrially and produced by plants and ...
Ellagic acid, a molecule at the core of naturally occurring phenolic compounds of varying sizes, is itself not a polyphenol by the WBSSH definition, but is by the Quideau definition. The raspberry ellagitannin , [ 8 ] on the other hand, with its 14 gallic acid moieties (most in ellagic acid-type components), and more than 40 phenolic hydroxyl ...
Phenolic acids are largely present in the pulp, anthocyanins and stilbenoids in the skin, and other phenols (catechins, proanthocyanidins and flavonols) in the skin and the seeds. [2] During the growth cycle of the grapevine , sunlight will increase the concentration of phenolics in the grape berries, their development being an important ...
Gallic acid (also known as 3,4,5-trihydroxybenzoic acid) is a trihydroxybenzoic acid with the formula C 6 H 2 (OH) 3 CO 2 H. It is classified as a phenolic acid. It is found in gallnuts, sumac, witch hazel, tea leaves, oak bark, and other plants. [1] It is a white solid, although samples are typically brown owing to partial oxidation.
Ferulic acid is a hydroxycinnamic acid derivative and a phenolic compound. It is an organic compound with the formula (CH 3 O)HOC 6 H 3 CH=CHCO 2 H. The name is derived from the genus Ferula, referring to the giant fennel (Ferula communis). Classified as a phenolic phytochemical, ferulic acid is an amber colored solid.
Phenolic is an adjective and a substantive (noun) that may apply to : Phenol (or carbolic acid), a colorless crystalline solid and aromatic compound. Phenols, a class of chemical compounds that include phenol. Phenolic content in wine. Phenolic paper, a type of cardboard used for printed circuit boards. Phenolic cotton cloth.
