- A peroxidase is one of a number of enzymes that act as catalysts to allow a variety of biological processes to take place. Specifically, they promote the oxidation of various compounds using naturally occurring peroxides, especially hydrogen peroxide (H 2 O 2), which are reduced, forming water.n fact, most of the the people that receive positive results on a thyroid peroxidase test (somewhere between 70 -90%) do indeed have chronic thyroidosis, however there are a some auto-immune disorders that can cause a false positive as well.

How Manganese Deficiency Impacts Enzyme Production Manganese superoxide dismutase is a powerful antioxidant, concentrated in your liver, kidneys, pancreas, pituitary gland and bones. It catalyzes the superoxide radical (a damaging kind of free radical) in your cell’s mitochondria into hydrogen peroxide, which is then broken down into water.

Peroxisomes - Another Enzyme Package Their enzymes attack complex molecules and break them down into smaller molecules. One of the byproducts of the digestion is hydrogen peroxide (H 2 O 2). Peroxisomes have developed to a point where they are able to contain that hydrogen peroxide and break it down into water (H 2 O) and oxygen (O 2). The water is harmless to the cell and the oxygen can be used in the next digestive reaction. Peroxisomes have a single membrane that surrounds the digestive enzymes and dangerous byproducts of their work (hydrogen peroxide). The protein enzymes are usually created by lysosomes floating in the cell. They then insert the proteins into the peroxisome bubble.

- Rating Newest Oldest. Best Answer: A major function of the peroxisome is the breakdown of fatty acid molecules, in a process called beta-oxidation. In this process, the fatty acids are broken down two carbons at a time, converted to Acetyl-CoA, which is then transported back to the cytosol for further use.n addition, when excess H2O2 accumulates in the cell, catalase converts it to H2O through this reaction.

Catalase Catalase is a common enzyme found in nearly all living organisms exposed to oxygen (such as bacteria, plants, and animals). It catalyzes the decomposition of hydrogen peroxide to water and oxygen. It is a very important enzyme in protecting the cell from oxidative damage by reactive oxygen species (ROS).

Peroxisomeupdate Certain enzymes within the peroxisome, by using molecular oxygen, remove hydrogen atoms from specific organic substrates (labeled as R), in an oxidative reaction, producing hydrogen peroxide (H 2 O 2, itself toxic):

- These enzymes also require co-factors such as selenium, iron, copper, zinc, and manganese for optimum catalytic activity. It has been suggested that an inadequate dietary intake of these trace minerals may compromise the effectiveness of these antioxidant defense mechanisms.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.

Antioxidant Oxidative damage in DNA can cause cancer. Several antioxidant enzymes such as superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, glutathione S-transferase etc. protect DNA from oxidative stress.

A Doctorâs Treasury of An antioxidant, like resveratrol, is any molecule that is stable with or without all its necessary electrons. A free radical, on the other hand, is a molecule that is unstable … when it loses an electron. The purpose of an antioxidant is to donate one of its electrons to the unstable free radicals.n its way round the body, the nutrients in the blood are absorbed into the places where they are needed. To sum this up, the body absorbs the nutrients into the blood through capillaries in the intestines.

What is the catalase test? Catalse Test Catalase (also known as peroxidase) is an enzyme that catalyses the breakdown of hydrogen peroxide to oxygen and water. Most higher organisms produce catalase, but in bacteriology this test is usually used to differentiate staphylococci (Catalase positive) from streptococci (Catalase negative).

What is a function of a peroxisome? Peroxisomes protect the cell from peroxide. Peroxide is a type of toxic waste. The peroxisomes turn the peroxide into food and oxygen! Hope this helped a little:)

Thyroid Peroxidase Test What is the thyroid peroxidase test. Thyroid peroxidase test is a test that measures the level of an antibody that is directed against thyroid peroxidase (TPO). Autoantibodies to thyroid peroxidase (TPOAb) are produced within the body. The presence of TPOAb in the blood reflects a prior attack on the thyroid tissue by the body's immune system.

Antioxidant An antioxidant is a molecule that inhibits the oxidation of other molecules. Oxidation is a chemical reaction involving the loss of electrons which can produce free radicals. In turn, these radicals can start chain reactions.When the chain reaction occurs in a cell, it can cause damage or death to the cell.ntioxidants terminate these chain reactions by removing free radical intermediates, and inhibit other oxidation reactions. They do this by being oxidized themselves, so antioxidants are often reducing agents such as thiols, ascorbic acid (vitamin C), or polyphenols.

Peroxisome (This is the ‘Lorenzo’s Oil’ connection – see later) Enzymes in peroxisomes also break down uric acid and amino acids. The decomposition of fatty acids by peroxisomes to the chemical acetyl CoA produces a great deal of metabolic energy and supplements that produced by mitochondria.
