Fumarate is a chemical compound that plays a crucial role in the body's metabolism. It is a type of dicarboxylic acid and is involved in the citric acid cycle, which is essential for energy production in cells. Fumarate can be formed from the conversion of succinate and is further processed into malate. In addition to its metabolic functions, fumarate is also studied for its potential therapeutic applications. For instance, fumaric acid esters are used in the treatment of certain skin conditions, such as psoriasis, and may have benefits in managing multiple sclerosis.
