| Common Name | Rapalexin B |
|---|
| Description | Rapalexin b is a member of the class of compounds known as hydroxyindoles. Hydroxyindoles are organic compounds containing an indole moiety that carries a hydroxyl group. Rapalexin b is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Rapalexin b can be found in chinese cabbage, which makes rapalexin b a potential biomarker for the consumption of this food product. |
