Gluconolactone

(3R,4S,5S,6R)-3,4,5-Trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-one

C6H10O6 (178.0477)


Gluconolactone, also known as glucono-delta-lactone or GDL (gluconate), belongs to the class of organic compounds known as gluconolactones. These are polyhydroxy acids (PHAs) containing a gluconolactone molecule, which is characterized by a tetrahydropyran substituted by three hydroxyl groups, one ketone group, and one hydroxymethyl group. Gluconolactone is a lactone of D-gluconic acid. Gluconolactone can be produced by enzymatic oxidation of D-glucose via the enzyme glucose oxidase. It is a fundamental metabolite found in all organisms ranging from bacteria to plants to animals. Gluconolactone has metal chelating, moisturizing and antioxidant activities. Its ability in free radicals scavenging accounts for its antioxidant properties. Gluconolactone, is also used as a food additive with the E-number E575. In foods it is used as a sequestrant, an acidifier or a curing, pickling, or leavening agent. Gluconolactone is also used as a coagulant in tofu processing. Gluconolactone is widely used as a skin exfoliant in cosmetic products, where it is noted for its mild exfoliating and hydrating properties. Pure gluconolactone is a white odorless crystalline powder. It is pH-neutral, but hydrolyses in water to gluconic acid which is acidic, adding a tangy taste to foods. Gluconic acid has roughly a third of the sourness of citric acid. One gram of gluconolactone yields roughly the same amount of metabolic energy as one gram of sugar. Food additive; uses include acidifier, pH control agent, sequestrant C26170 - Protective Agent > C275 - Antioxidant D-(+)-Glucono-1,5-lactone is a polyhydroxy (PHA) that is capable of metal chelating, moisturizing and antioxidant activity.

   

L-Gulonolactone

C6H10O6 (178.0477)


L-Gulonolactone (also known as reduced ascorbic acid, RAA) is the substrate of the enzyme L-gulono-1,4-lactone oxidoreductase (EC 1.1.3.8), which catalyzes the last step of the biosynthesis of L-ascorbic acid (vitamin C) in plants and animals. The enzyme L-Gulono-1,4-lactone oxidase is missing in scurvy-prone, vitamin C-deficient animals, such as humans. L-Gulonolactone is present in human blood and has been used as one of the markers to compare changes in exercise-induced oxidative stress.

Galactonolactone

Galactonolactone has been determined in human urine by reversed-phase HPLC for the specific evaluation of metabolic by-products in the urine of galactosemic patients and based on the simultaneous determination of gluconolactone, galactonolactone and galactitol. (PMID: 1797843). Patients with galactose-1-phosphate uridyltransferase (GALT) deficiency, given a load of galactose have been shown to excrete six times as much galactonate in their urine as normal subjects exposed to the same experimental conditions. The production of galactonate occurs through the activity of a soluble NAD+-dependent galactose dehydrogenase, catalyzing the conversion of galactose to D-galactonolactone (D-galactose: NAD+ oxidoreductase, EC 1.1.1.48). (OMMBID). Galactonolactone has been determined in human urine by reversed-phase HPLC for the specific evaluation of metabolic by-products in the urine of galactosemic patients and based on the simultaneous determination of gluconolactone, galactonolactone and galactitol.
