Metabolite Identification
Common NameAcetamide
DescriptionAcetamide, also known as ethanamid or acetic acid amide, belongs to the class of organic compounds known as carboximidic acids. These are organic acids with the general formula RC(=N)-OH (R=H, organic group). Acetamide is a mousy tasting compound. Acetamide has been detected, but not quantified in, red beetroots (Beta vulgaris var. rubra). This could make acetamide a potential biomarker for the consumption of these foods. Acetamide is formally rated as a possible carcinogen (by IARC 2B) and is also a potentially toxic compound. Based on a literature review a significant number of articles have been published on Acetamide.
