(R,S)-Equol-d4 (Major)(Mixture of Diastereomers)

(R,S)-Equol-d4 is a stable isotope-labeled mixture of diastereomers of Equol, a compound that is produced by the metabolism of soy isoflavones in the gut. It is a chiral molecule, meaning that it exists in two mirror-image forms or enantiomers. The (R,S) designation indicates that the mixture contains both enantiomers, which are present in equal amounts. Equol-d4 is used as an analytical standard in research studies to study the metabolism, pharmacokinetics, and bioavailability of Equol in humans and animals. Chemically, (R,S)-Equol-d4 has the molecular formula C15H13D4NO3. It has a molecular weight of 269.35 g/mol and a melting point of 165-167 °C. Equol-d4 is a white to off-white powder that is soluble in organic solvents such as methanol and ethanol. The biological activity of Equol-d4 is similar to that of natural Equol, which has been shown to have a range of health benefits, including anti-inflammatory, antioxidant, and anti-cancer properties. However, the effects of Equol-d4 on human health are not well studied, as it is primarily used as a research tool. Studies have shown that Equol-d4 is rapidly absorbed and metabolized in the body, with a half-life of approximately 4 hours. It is excreted primarily in the urine and feces.
