Metabolite Identification
Common NameCamalexin
DescriptionCamalexin belongs to the class of organic compounds known as indoles. Indoles are compounds containing an indole moiety, which consists of pyrrole ring fused to benzene to form 2,3-benzopyrrole. Camalexin has been detected, but not quantified in, several different foods, such as soft-necked garlics (Allium sativum L. var. sativum), chanterelles (Cantharellus cibarius), spelts (Triticum spelta), cardamoms (Elettaria cardamomum), and sour oranges (Citrus × aurantium). This could make camalexin a potential biomarker for the consumption of these foods. Camalexin is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review a significant number of articles have been published on Camalexin.
