Maleic acid and fumaric acid are cis-trans isomers of each other.
Fumaric acid being the trans isomer will have the least stearic hindrance as the carboxylic acid groups will be on the different sides of the double bonds-hence causing the least electronic repulsion. Fumaric acid will be more stable as compared to maleic acid.

Malic Acid, Citric acid, Isocitric Acid, Succinic Acid and Fumaric Acid.
just tried it. a dash of reagent grade fumaric acid was covered in janator strength non detergent ammonia. no observable reaction....
Fumaric acid is dried in an oven at a relatively low heat - below 130 degrees centigrade - to evaporate any water that might be left over from formation. If it is heated above 130 degrees, the fumaric acid starts to decompose and form maleic acid, maleic anhydride, carbon monoxide and carbon dioxide. The acid may be dried for a number of reasons. Commercially because water has weight but no value, it is cheaper to transport completely dry fumaric acid. Water may also cause unwanted reactions with other chemicals which the fumaric acid is eventually added to. Removing the water then removes the reactions.
Jello is one of the foods that are low in purines and therefore dont make a great deal of uric acid in the system.
An aspartase is an enzyme which catalyzes the deamination of aspartic acid to fumaric acid and ammonia.
You should avoid too much niacin when you have gout as the niacin competes with the means the body has for eliminating uric acid,
trans-butenedioic acid,C4H4O4 also called fumaric acid
No gout is caused by uric acid.
