What is Adipic acid?

Adipic acid is an alpha,-dicarboxylic acid that is the 1,4-dicarboxy derivative of butane. It has a role as a food acidity regulator and a human xenobiotic metabolite. It is a dicarboxylic fatty acid and an alpha,omega-dicarboxylic acid. It is a conjugate acid of an adipate(1-).
