Equol [7-hydroxy(4 0 -hydroxyphenyl)-chroman] is the most well-known phenolic microbial metabolite with a variety of biological properties (Setchell and.
Equol (7-hydroxy-3[4'hydroxyphenyl]-chroman) is the major metabolite of the phytoestrogen daidzein, one of the main isoflavones found abundantly in soybeans and soy foods. Estrogen deficiency has been well characterized in inflammatory disorders including neuroinflammation. Daidzein, a dietary alternative phytoestrogen found in soy (Glycine max) as primary isoflavones, possess anti‐inflammatory activity, but the effect of its active metabolite Equol (7‐hydroxy‐3‐(4′‐hydroxyphenyl)‐chroman) has not been well by: The discrepancy may be due to the much lower prevalence of S-equol producers in Westerners: Only % of Westerners produce S-equol in contrast to % in Asians.
S-equol is a metabolite of dietary soy isoflavone daidzein by gut microbiome and possesses the most antiatherogenic properties among all by: 5. In a larger follow-up study, 50 postmenopausal women (age range: 51–66 years) completed a 6-week intervention of 60 mg isoflavones per treatment, women receiving the soy supplement performed better than the placebo group on measures of non-verbal short-term memory, planning ability and mental flexibility (see Fig.

Equol (4',7-isoflavandiol) is an isoflavandiol estrogen metabolized from daidzein, a type of isoflavone found in soybeans and other plant sources, by bacterial flora in the intestines. While endogenous estrogenic hormones such as estradiol are steroids, equol is a nonsteroidal r, only about % of people have intestinal bacteria that make Number: Equol [7-hydroxy(4'-hydroxyphenyl)-chroman] is a nonsteroidal estrogen of the isoflavone class.
It is exclusively a product of intestinal bacterial metab. of dietary isoflavones and it possesses estrogenic activity, having affinity for both estrogen receptors, ERα and ERβ. Equol is superior to all other isoflavones in its antioxidant by: B.

Equol (C 15 H 14 O 3) and O-DMA (C 15 H 14 O 4) are specific metabolites from daidzein (), which have the unabsorbed portion hydrogenated, leading to the formation of dihydrodaidzein (DHD), and this compound is then converted into O-DMA or equol (Bowey et al.,Chang and Nair,Yuan et al., ).Equol is formed exclusively by gut bacteria (Bowey et al.,Cited by: 2.

Equol, one of the main metabolites of daidzein, is a chiral compound with pleiotropic effects on cellular signaling. This property may induce activation/inhibition of the estrogen receptors (ER) a or b, and therefore, explain the beneficial/deleterious effects of equol on estrogen-dependent diseases.
