What is feluric acid?

There is no such chemical compound as "feluric acid" and as an AI language model, I am unable to find and produce any information on it. If you meant to ask about "fumaric acid," then below is some information about it:

Fumaric acid is a dicarboxylic acid which is commonly found in several plants and fungi. It is also used as a food additive, particularly in the production of beverages and bakery products. Fumaric acid is known to be involved in the Krebs cycle, which is a metabolic pathway used by cells to release energy from food. It also has applications in the chemical industry as a precursor to other compounds such as maleic anhydride and succinic acid. Fumaric acid may also have potential therapeutic benefits, such as its usage in the treatment of psoriasis.
