In organic chemistry, phenols, sometimes called phenolics, are a class of chemical compounds consisting of one or more hydroxyl groups (−O H) bonded directly to an aromatic hydrocarbon group. [1] 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 ...
Phenols are aromatic compounds with a hydroxyl functional group. ... Phenolic human metabolites (22 P) Phenolic lipids (2 C, 3 P) Polyphenols (4 C, 65 P) S.
Phenolic compounds, when used in beverages, such as prune juice, have been shown to be helpful in the color and sensory components, such as alleviating bitterness. [ 102 ] Some advocates for organic farming claim that organically grown potatoes , oranges , and leaf vegetables have more phenolic compounds and these may provide antioxidant ...
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 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).
The process of maceration or extended skin contact allows the extraction of phenolic compounds from the skins of the grape into the wine. In red wine, up to 90% of the wine's phenolic content falls under the classification of flavonoids. These phenols, mainly derived from the stems, seeds and skins are often leached out of the grape during the ...
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 ...
Natural polyphenols molecular formulas represent a class of natural aromatic organic compounds in which one or more hydroxy groups are attached directly to the benzene ring, generally formed from C, H and O. [1] The entries are sorted by mass.
