Glucic acid
Glucic acid is an organic compound with the chemical formula C3H4O3. It is classified as a reductone.
Production
Glucic acid is produced by heating fructose under alkaline conditions. Under acidic conditions, levulinic acid is produced instead.It also occurs in the hydrolysis of sucrose under alkaline conditions as prolonged heating causes the resulting hexoses to further decompose into several compounds, including glucic acid.
