The D- glucaric acid is a polyhydroxy dicarboxylic acid ( see Fischer projection on stereoisomerism ). It belongs to the aldaric. Technical glucaric acid is usually also as a sugar acid (in the narrow sense) called (see also sugar acids in the broad sense ). Its salts and esters hot glucarate or technically saccharates (but see sugar esters ).

Aqueous solutions of glucaric acid exhibit the phenomenon of mutarotation.

Production

Glucaric acid is produced by oxidation of D- glucose, sucrose or starch with concentrated nitric acid.

Occurrence

Glucaric acid comes from a branch of ascorbic acid synthesis and occurs among other fruits and vegetables such as bean sprouts, buckthorn plants, grapes, apples and grapefruits.

Use

It is sometimes used as a complexing agent. Your 4 - lactone is a strong glucuronidase inhibitor. The use of glucaric acid as a starting material for the chemical industry is currently working in applied research (white biotechnology) intensively.
