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 ...
Polyphenols (/ ˌpɒliˈfiːnoʊl, - nɒl /) are a large family of naturally occurring phenols. [ 1 ] They are abundant in plants and structurally diverse. [ 1 ][ 2 ][ 3 ] Polyphenols include phenolic acids, flavonoids, tannic acid, and ellagitannin, some of which have been used historically as dyes and for tanning garments.
Phenol (also known as carbolic acid, phenolic acid, or benzenol) is an aromatic organic compound with the molecular formula C6H5OH. [ 5 ] It is a white crystalline solid that is volatile. The molecule consists of a phenyl group (−C6H5) bonded to a hydroxy group (−OH).
Furthermore, flavonoids can be found in plants in glycoside-bound and free aglycone forms. The glycoside-bound form is the most common flavone and flavonol form consumed in the diet. [1] A biochemical diagram showing the class of flavonoids and their source in nature through various inter-related plant species.
Definition. Phytochemicals are chemicals of plant origin. [ 1 ] Phytochemicals (from Greek phyto, meaning "plant") are chemicals produced by plants through primary or secondary metabolism. [ 2 ][ 3 ] They generally have biological activity in the plant host and play a role in plant growth or defense against competitors, pathogens, or predators.
A polyphenol antioxidant is a hypothesized type of antioxidant studied in vitro. Numbering over 4,000 distinct chemical structures mostly from plants, such polyphenols have not been demonstrated to be antioxidants in vivo. [1][2][3] In vitro at high experimental doses, polyphenols may affect cell-to-cell signaling, receptor sensitivity ...
