Metabolite Identification
Common NameIminoaspartic acid
DescriptionIminoaspartic acid, also known as iminosuccinate or iminoaspartate, belongs to the class of organic compounds known as dicarboxylic acids and derivatives. These are organic compounds containing exactly two carboxylic acid groups. Iminoaspartic acid exists in all living species, ranging from bacteria to plants to humans. Iminoaspartic acid has been detected, but not quantified in, a few different foods, such as anatidaes (Anatidae), chickens (Gallus gallus), and domestic pigs (Sus scrofa domestica). This could make iminoaspartic acid a potential biomarker for the consumption of these foods. Iminoaspartic acid 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 Iminoaspartic acid.
