Polyphenols ⇒ Proanthocyanidins {90000374} Record Keys Parent:Polyphenols Definition:Proanthocyanidins Queue:[ ] Details Initialisation date:[ ] Specification: [ ]Source: [ ] Meta Information Structural Type:[ ] Functional Type:[ ] Function:[ ] Notes: [ ]Shared Reference Notes [1.1] - Proanthocyanidins are biotransformed by #Adlercreutzia equolifaciens JCM 14793T, #Eubacterium sp. SDG-2, #Eggerthella lenta rK3 and #Eggerthella lenta CAT-1 and from the phylum actinomycetes, which belong to the phylum #Actinobacteria, through the cleavage of the C-ring and dihydroxylation reactions to produce (−)EGC, (−)-gallocatechin (GC), (±)EC and (±)-catechin (C) [1.2] [#Catechins, #Epicatechins] - Epicatechin, catechin and the proanthocyanidins are the main flavan-3-ols metabolized by the gut microbiota that also elicit beneficial anti-inflammatory effects. [1.3] [#Polyphenols] - flavan-3-ols, particularly A-type proanthocyanidins, were the most abundant polyphenol class in the #Cranberry extract - #Cranberry flavan-3-ols are mainly A-type oligomeric proanthocyanidins, which are poorly degraded in the gutReferences Notes[ ]
