Monocyclic Phenolic Acids; Hydroxy- and Polyhydroxybenzoic Acids: Occurrence and Recent Bioactivity Studies

Monocyclic phenolic acids; hydroxy- and polyhydroxybenzoic acids: occurrence and recent bioactivity studies.

Among the wide diversity of naturally occurring phenolic acids, at least 30 hydroxy- and polyhydroxybenzoic acids have been reported in the last 10 years to have biological activities. The chemical structures, natural occurrence throughout the plant, algal, bacterial, fungal and animal kingdoms, and recently described bioactivities of these phenolic and polyphenolic acids are reviewed to illust...

Fatty Acids: Hydroxy and Other Oxygenated Structures, Occurrence and Biochemistry

The following is a guide to the more important naturally occurring fatty acids with hydroxy, epoxy (furanoid), methoxy and oxo substituents, but it is not intended to be a comprehensive list. The prostaglandins and other eicosanoids and the plant oxylipins are in essence fatty acids with additional oxygenated functional groups, but these are discussed elsewhere in this website. Similarly, hydro...

Bioactivity of phenolic acids: metabolites versus parent compounds: a review.

Phenolic acids are present in our diet in different foods, for example mushrooms. Due to their bioactive properties, phenolic acids are extensively studied and there is evidence of their role in disease prevention. Nevertheless, in vivo, these compounds are metabolized and circulate in the organism as glucuronated, sulphated and methylated metabolites, displaying higher or lower bioactivities. ...
