Fumaric acid lossis trans-butenedioic acid yog cov tshuaj sib xyaw nrog cov mis HO2CCH=CHCO2H. Qhov dawb crystalline compound yog ib ntawm ob isomeric unsaturated dicarboxylic acids, lwm qhov yog maleic acid. Hauv fumaric acid pawg carboxylic acid yog trans (E) thiab hauv maleic acid lawv yog cis (Z). Fumaric acid muaj cov txiv ntoo zoo li saj. Cov ntsev thiab esters raug hu ua fumarates.
