Metabolite Identification
Common NameAvenanthramide 2
DescriptionAvenanthramide 2 belongs to the class of organic compounds known as avenanthramides. These are a group of phenolic alkaloids consisting of conjugate of three phenylpropanoids (ferulic, caffeic, or p-coumaric acid) and anthranilic acid. Avenanthramide 2 has been detected, but not quantified in, a few different foods, such as breakfast cereal, cereals and cereal products, and oats (Avena sativa). This could make avenanthramide 2 a potential biomarker for the consumption of these foods. Based on a literature review a significant number of articles have been published on Avenanthramide 2.
