Cysteinylglycine
Cysteinylglycine is a naturally occurring dipeptide. It is derived from the breakdown of glutathione (a tripeptide). In plasma, cysteinylglycine is in a reduced, oxidized and protein-bound form (aminothiol) and interact via redox and disulphide exchange reactions, in a dynamic system referred to as redox thiol status. (PMID 8642471) Spermatozoa of sub fertile men contain significantly higher thiol concentrations as compared with those of fertile men. The detrimental effect on embryo quality of a high homocysteine (Hcy, another member of the thiol group) concentration in the ejaculate and in follicular fluid is intriguing and may suggest that Hcy is inversely associated with fertility outcome. (PMID 16556671) Rheumatoid arthritis (RA) is a chronic inflammatory disease which involves the synovial membrane of multiple diarthroidal joints causing damage to cartilage and bones. The damage process seems to be related to an overproduction of oxygen reactive species inducing an oxidative perturbation with an increase in some oxidized forms (disulfides and protein mixed disulfides) and a decrease in free thiols. (PMID 15895891) Imipenem (thienamycin formamidine), is a broad-spectrum beta-lactam antibiotic, always used in combination with cilastatin in order to avoid the premature breakdown of imipenem by renal tubular dipeptidase. As this dipeptidase also hydrolyzes the glutathione metabolite cysteinylglycine, the therapeutic association of imipenem and cilastatin causes plasma levels of cysteinylglycine to increase significantly, while cysteine levels are decreased and homocysteine levels are unaffected. Therefore, antibiotic treatment using imipenem-cilastatin induces important metabolic changes that should not remain unrecognized. (PMID 15843241) [HMDB]. Cysteinylglycine is found in many foods, some of which are chinese cabbage, wax apple, garden tomato (variety), and japanese pumpkin.

Gluconolactone
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.

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).
