WebJan 1, 2024 · Biosynthesis of phenols and polyphenols. As we saw from the classification, phenols vary from simple aromatic rings like flavones to highly complex compounds like lignin. For all these phenol compounds, phenylalanine is the common precursor and hence they are also known as phenylpropanoids (Nanda et al., 2016). WebAug 29, 2024 · 22.3.1 Flavonoids. Flavonoids are the largest group of secondary metabolites, which are derivatives of simple phenols. Structurally they have a 15-carbon skeleton, consisting of two aromatic rings connected by three carbon bridge (C6–C3–C6) (Kulbat 2016).Structural and functional differentiation of flavonoids depends on its …

WebProperties Acidity. Phenols are more acidic than typical alcohols. The acidity of the hydroxyl group in phenols is commonly intermediate between that of aliphatic alcohols and carboxylic acids (their pK a is usually between 10 and 12). Deprotonation of a phenol forms a corresponding negative phenolate ion or phenoxide ion, and the corresponding salts …
