toralactone

Description

Toralactone belongs to the class of organic compounds known as naphthopyranones. Naphthopyranones are compounds containing a naphthopyran skeleton where a ring carbon bears a carboxylic acid group. Naphthtopyran is made up of the pyran ring fused to a naphthalene ring system. Toralactone has been detected, but not quantified in, several different foods, such as arabica coffees (Coffea arabica), coffee and coffee products, herbs and spices, pulses, and robusta coffees (Coffea canephora). This could make toralactone a potential biomarker for the consumption of these foods. Toralactone 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 Toralactone.
