What is Glutaric acid?

Glutaric acid is an alpha,-dicarboxylic acid that is a linear five-carbon dicarboxylic acid. It has a role as a human metabolite and a Daphnia magna metabolite. It is a dicarboxylic fatty acid and an alpha,omega-dicarboxylic acid. It is a conjugate acid of a glutarate and a glutarate(1-).
