Common_Nametrans-trans-Muconic acid
Descriptiontrans,trans-Muconic acid is a urinary metabolite of benzene and has been used as a biomarker of exposure to benzene in humans exposed to levels as low as 1 ppm. However, muconic acid is known that may also be derived from sorbic acid and its salts. Dietary supplementation with 500 mg sorbic acid significantly increases the urinary trans,trans-Muconic acid excretion. Under study conditions 0.12% of the sorbic acid dose is excreted in urine as trans, trans muconic acid thereby indicating that a typical dietary intake of 6 - 30 mg/day of sorbic acid accounts for 10 -50% of the background of trans, trans muconic acid excretion in nonsmokers, and for 5 - 25% in smokers.
