Common Name | Oryzalexin E |

Description | Oryzalexin E belongs to the class of organic compounds known as hydrophenanthrenes. These are a phenanthrene derivative where at least one ring CC bond is substituted by hydrogenation. Oryzalexin E has been detected, but not quantified in, rice (Oryza sativa). This could make oryzalexin e a potential biomarker for the consumption of these foods. Oryzalexin E is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a significant number of articles have been published on Oryzalexin E. |
