Metabolite Identification

Common Name

Lettucenin A

Description

Lettucenin A belongs to the class of organic compounds known as cycloheptafurans. These are organic heterocyclic compounds containing a cycloheptane derivative fused to a furan. Furan is a five-membered aromatic ring with four carbon atoms and one oxygen atom. Lettucenin A has been detected, but not quantified in, lettuces (Lactuca sativa) and romaine lettuces (Lactuca sativa L. var. longifolia). This could make lettucenin a a potential biomarker for the consumption of these foods. Based on a literature review a small amount of articles have been published on Lettucenin A.
