Enterolactone
Enterolactone (CAS: 78473-71-9) is a mammalian lignan that has a similar biphenolic structure to lignans from plants. Lignans are compounds with estrogenic properties and are probably the most important source of phytoestrogens in western diets. Mammalian lignans are formed from precursors that are contained mainly in vegetables, whole grain products, and berries, via the action of intestinal microflora. Enterolactone is produced in the colon by the action of bacteria on secoisolariciresinol, matairesinol, and its glycosides. Secoisolariciresinol is converted to enterodiol which is subsequently converted to enterolactone as it passes through the colon. Matairesinol is converted directly to enterolactone. Enterolactone has been shown to possess weakly estrogenic and antiestrogenic activities, and it has been suggested that the high production of this antiestrogenic mammalian lignans in the gut may serve to protect against breast cancer in women and prostate cancer in men; however epidemiological evidence to date is conflicting (PMID: 16168401, 12270221, 11216511, 12107024). Enterolactone is a biomarker for the consumption of soybeans and other soy products. D006730 - Hormones, Hormone Substitutes, and Hormone Antagonists > D006728 - Hormones > D004967 - Estrogens
(+)-Ligballinol
(+)-ligballinol is a member of the class of compounds known as furanoid lignans. Furanoid lignans are lignans with a structure that contains either a tetrahydrofuran ring, a furan ring, or a furofuan ring system, that arises from the joining of the two phenylpropanoid units (+)-ligballinol is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). (+)-ligballinol can be found in pulses, which makes (+)-ligballinol a potential biomarker for the consumption of this food product. (+)-Ligballinol is found in pulses. (+)-Ligballinol is a stress metabolite of cell cultures of Vigna angularis (azuki bean

7C-aglycone
7C-aglycone is one of the two major aglycone urinary water-soluble metabolites of Phylloquinone (Vitamin K1) and menaquinones (vitamin K2), usually excreted as glucuronide conjugates; their structure suggests that they are formed by an oxidative degradation of the phytyl side chain involving enzymes of omega- and beta-oxidation. Newborn infants as a group, are known to have precariously low vitamin K stores and are routinely given vitamin K prophylaxis at birth.
