Chemical Information
FooDB NameZeanic acid
DescriptionZeanic acid, also known as zeanate, belongs to the class of organic compounds known as quinoline carboxylic acids. These are quinolines in which the quinoline ring system is substituted by a carboxyl group at one or more positions. Zeanic acid has been detected, but not quantified in, breakfast cereal and cereals and cereal products. This could make zeanic acid a potential biomarker for the consumption of these foods. Based on a literature review very few articles have been published on Zeanic acid.
