Metabolite Identification
Common NameD-Araboascorbic acid
DescriptionD-isoascorbic acid, also known as D-erythorbic acid or araboascorbate, belongs to the class of organic compounds known as butenolides. These are dihydrofurans with a carbonyl group at the C2 carbon atom. One such trial investigated the effects of erythorbic acid on vitamin C metabolism in young women; no effect on vitamin C uptake or clearance from the body was found. It is also used as a preservative in cured meats and frozen vegetables. D-isoascorbic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). It can also be synthesized from sucrose or by strains of Penicillium that have been selected for this feature. It is synthesized by a reaction between methyl 2-keto-D-gluconate and sodium methoxide. It is denoted by E number E315, and is widely used as an antioxidant in processed foods. Since the U.S. Food and Drug Administration banned the use of sulfites as a preservative in foods intended to be eaten fresh (such as salad bar ingredients), the use of erythorbic acid as a food preservative has increased. Clinical trials have been conducted to investigate aspects of the nutritional value of erythorbic acid. It was first synthesized in 1933 by the German chemists Kurt Maurer and Bruno Schiedt. A later study found that erythorbic acid is a potent enhancer of nonheme-iron absorption. Erythorbic acid (isoascorbic acid, D-araboascorbic acid) is a stereoisomer of ascorbic acid (vitamin C).
