Urinary metabolite of daidzein, produced by humans and horses. Heinonen, S., et al. While the chemical properties of the single isomer form are essentially identical to those of the racemic mixture (except for rotation of plane polarized light, melting point, and so on), the biological properties of the single-isomer, naturally-occurring form are quite likely to be somewhat different from those of the racemic mixture.
This product is a racemic mixture of the R- and S-enantiomers. However, the naturally-occurring form of equol from horse urine consists of a single stereoisomer.
