Xanthine oxidase Xanthine oxidase (XO, sometimes 'XAO') is a form of xanthine oxidoreductase, a type of enzyme that generates reactive oxygen species.These enzymes catalyze the oxidation of hypoxanthine to xanthine and can further catalyze the oxidation of xanthine to uric acid.anthine oxidase is a superoxide-producing enzyme found normally in serum and the lungs, and its activity is increased during influenza A infection. During severe liver damage, xanthine oxidase is released into the blood, so a blood assay for XO is a way to determine if liver damage has happened.

- A glucoamylase enzyme is used to break down the starch molecules and the dextrins. This enzyme is capable of achieving the complete degradation of the starch to fermentable sugars (glucose). During fermentation, these sugars are converted into alcohol by yeast in simultaneous saccharification and fermentation process. glucoamylase enzyme is used to break down the starch molecules and the dextrins.

Kidney disease Another possible cause of Kidney disease is due to decreased function of xanthine oxidase in the purine degradation pathway. Xanthine oxidase will degrade hypoxanthine to xanthine and then to uric acid.

Acetylcholinesterase inhibitor Acetylcholinesterase inhibition. An acetylcholinesterase inhibitor (often abbreviated AChEI) or anti-cholinesterase is a chemical or a drug that inhibits the acetylcholinesterase enzyme from breaking down acetylcholine, thereby increasing both the level and duration of action of the neurotransmitter acetylcholine.ome major effects of cholinesterase inhibitors: 1  Actions on the parasympathetic nervous system, (the parasympathetic branch of the autonomic nervous system) may cause bradycardia, hypotension, hypersecretion, bronchoconstriction, GI tract hypermotility, and decrease intraocular pressure.

What does Peroxidase do? Report Abuse. A peroxidase (eg. EC 1.11.1.9) is an enzyme, which may contain heme, that catalyzes a reaction of the form: ROOR' + electron donor (2 e-) + 2H+ → ROH + R'OH For many of these enzymes the optimal substrate is hydrogen peroxide, but others are more active with organic hydroperoxides such as lipid peroxides.ytochrome c peroxidase is used as a soluble, easily purified model for cytochrome c oxidase. Glutathione peroxidase is a peroxidase found in humans, which contains selenocysteine. It uses glutathione as an electron donor and is active with both hydrogen peroxide and organic hydroperoxide substrates.

Monoamine oxidase L-Monoamine oxidases (MAO) (EC 1.4.3.4) are a family of enzymes that catalyze the oxidation of monoamines.They are found bound to the outer membrane of mitochondria in most cell types in the body.xygen is used to remove an amine group from a molecule, resulting in the corresponding aldehyde and ammonia. Monoamine oxidases contain the covalently bound cofactor FAD and are, thus, classified as flavoproteins.

Antioxidant Of these glutathione peroxidase is an enzyme containing four selenium-cofactors that catalyzes the breakdown of hydrogen peroxide and organic hydroperoxides. Glutathione ''S''-transferases show high activity with lipid peroxides. These enzymes are at particularly high levels in the liver.hese form the body’s endogenous defence mechanisms to help protect against free radical-induced cell damage. The antioxidant enzymes – glutathioneperoxidase, catalase, and superoxide dismutase (SOD) – metabolize oxidative toxic intermediates.

- In most plants, the yellow coloration is masked by the presence of chlorophyll, and xanthophylls are only revealed when chlorophyll is degraded when the leaf has become senescent (Example: Justicia). These yellow pigments are also observed in leaves with certain nutrient deficiencies (see chlorosis).n a process called the xanthophyll cycle, a cellular pool of violaxanthin (a diepoxide) is present in the plastids at dawn, and that compound is changed through an intermediary compound called antheraxanthin (a monoepoxide) into zeaxanthin (epoxide-free) as sunlight intensity increases.

- Xanthophylls. Xanthophylls are the typical yellow pigments of leaves. These are oxygenated carotenoids that are synthesized within the plastids. Xanthophylls do not require light for synthesis, so that xanthophylls are present in all young leaves as well as in etiolated leaves.n a process called the xanthophyll cycle, a cellular pool of violaxanthin (a diepoxide) is present in the plastids at dawn, and that compound is changed through an intermediary compound called antheraxanthin (a monoepoxide) into zeaxanthin (epoxide-free) as sunlight intensity increases.

What Every Doctor Should Know About Glutathione It has also been called the Great Protector, and the Mother of Antioxidants with good reason. In addition to being an antioxidant, glutathione is also a powerful detoxifier and also plays a major role in immune function. Glutathione (GSH) is a tripeptide comprised of the amino acids glutamine, cysteine and glycine.It is a naturally occurring protein made by and used by every cell in the body.trategies for repletion include the use of glutathione precursors such as N-acetyl cysteine and whey protein, which can also provide cysteine in the oxidized form called cystine. Studies are now ongoing to assess the absorption and impact of supplementation with liposomal glutathione.
