Common Name2-Aminoadipic acid
DescriptionAminoadipic acid, also known as a-aminoadipate or Aad, belongs to the class of organic compounds known as alpha amino acids. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Aminoadipic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Aminoadipic acid exists in all eukaryotes, ranging from yeast to humans. Within humans, aminoadipic acid participates in a number of enzymatic reactions. In particular, aminoadipic acid can be biosynthesized from allysine; which is mediated by the enzyme Alpha-aminoadipic semialdehyde dehydrogenase. In addition, aminoadipic acid and oxoglutaric acid can be converted into oxoadipic acid and L-glutamic acid; which is catalyzed by the enzyme kynurenine/alpha-aminoadipate aminotransferase, mitochondrial. In humans, aminoadipic acid is involved in the metabolic disorder called 2-aminoadipic 2-oxoadipic aciduria. Outside of the human body, Aminoadipic acid is found, on average, in the highest concentration within a few different foods, such as wheats, milk (cow), and ryes and in a lower concentration in dills, garden onions, and white cabbages. Aminoadipic acid has also been detected, but not quantified in, several different foods, such as barley, cow milks, cow milks, cow milks, and cow milks. This could make aminoadipic acid a potential biomarker for the consumption of these foods. Aminoadipic acid is a potentially toxic compound. Aminoadipic acid, with regard to humans, has been found to be associated with several diseases such as alpha-aminoadipic and alpha-ketoadipic aciduria, colorectal cancer, metastatic melanoma, and eosinophilic esophagitis; aminoadipic acid has also been linked to the inborn metabolic disorder 2-ketoadipic acidemia.
