Biochemical processes related to catalase 5

Catalase is a stable oxygenase refined by biological extraction. Its role is to efficiently decompose hydrogen peroxide (hydrogen peroxide). This product can be widely used in the biological deoxidation purification process after oxygen bleaching of textiles.

That is, before dyeing, the hydrogen peroxide that remains in the textile and its process environment after oxygen bleaching is removed. The significance of this is that it can efficiently and quickly remove residual hydrogen peroxide from fabrics and water baths after oxygen bleaching with significant savings in water resources and other energy sources. In order to avoid the destruction of the dye by the residual hydrogen peroxide, there will be dyeing defects.

The product can effectively improve the dyeing quality, shorten the process time, and reduce the emission of three wastes. The company's [catalase - industrial agent] is a pure natural enzyme extracted from animal organs by high-tech means, and the product is light brown in color and slightly odorous. Its performance is superior, the quality is excellent, is the current printing and dyeing industry outside China similar products of the excellent substitute.

The enzyme is also suitable for use in hotels, hospitals, laundry rooms, etc., textiles that use hydrogen peroxide for bleaching or disinfection. Prevent the existence of residual hydrogen peroxide in the fabric, which causes the user's allergies, inflammation and other adverse consequences, and also avoids the oxidation and brittleness of the fabric, so as to prolong the service life.

It is said that there are many catalases in the liver, so please ask him.

Asking for extra points, this problem can't be bought with 5 points

I'm a biology major.

Peroxidase is a type of antioxidant enzyme system, which has the ability to scavenge reactive oxygen species.

features. Examples and brothers such as:

Hydrogen peroxide, which is produced by organisms during biochemical reactions, can be broken down into water and oxygen by catalase.

Superoxide dismutase.

It is the body's defense against the internal and external environment.

An important enzyme for oxygen ion damage.

Glutathione peroxidase is an indispensable enzyme in the body to prevent damage from reactive oxygen species, and can remove hydrogen peroxide and other peroxides.

1. Catalytic hydrogen peroxide decomposition: hydrogen peroxide is a waste product produced in the metabolic process, which can cause damage to the body. To avoid this damage, hydrogen peroxide must be rapidly converted into other harmless or less toxic substances. And catalase.

It is often used by cells to catalyze the decomposition of hydrogen peroxide.

2. Make an effective antimicrobial reagent: cells are pathogens.

In infection, hydrogen peroxide can be used as an effective antimicrobial agent. Some pathogens, such as Mycobacterium tuberculosis.

Legionella pneumophila and Campylobacter jejuni produce catalase to degrade hydrogen peroxide, allowing them to survive in the host.

Based on the literature, my understanding is that peroxidase catalyzes hydrogen peroxide productionHydroxyl radicals；Whereas, catalase catalizes the production of hydrogen peroxideOxygen

Peroxygenation in cells.

Physiological function of copy enzyme: an enzyme that catalyzes substrate oxidation with hydrogen peroxide as an electron acceptor, can catalyze many reactions. It is mainly found in the peroxisomes of cells, with iron porphyrins as the auxiliary group, which can catalyze the oxidation of phenolic and amine compounds by hydroxide, and has the dual effect of eliminating the toxicity of hydrogen peroxide and phenols and amines.

Peroxisomes are vesicles encased in a membrane of units and are approximately in diameter, usually smaller than mitochondria. It is ubiquitous in all types of eukaryotic cells, especially in hepatocytes and kidney cells.

The hallmark enzyme of peroxisomes is catalase, which mainly hydrolyzes hydrogen peroxide. Hydrogen peroxide is a cytotoxic substance produced in oxidase-catalyzed redox reactions, both oxidases and catalases are present in peroxisomes, thus playing a protective role in cells.

Peroxybaicarase is over.

Hydrogen oxide is an electron acceptor.

Du is an enzyme that catalyzes substrate oxidation, which can catalyze many reactions of DAO. It mainly exists in the peroxide asisosome of cells, with iron porphyrin as the prosthetic group, which can catalyze the oxidation of phenolic and amine compounds by hydroxide, and has the dual effect of eliminating the toxicity of hydrogen peroxide and phenols and amines. It is also involved in physiological processes such as the breakdown of fatty acids, the metabolism of nitrogenous substances, and the regulation of oxygen concentration.

Peroxidation in animals.

Biosomes are involved in the oxidation of fatty acids (the other organelle is mitochondria), and the concentration of peroxisomes in rat hepatocytes increased by 10-fold after taking Lilipid-lowering Lingrong. In addition, peroxisomes also have a detoxification effect, because catalase can use H2O2 to oxidize harmful substances such as phenols, formaldehyde, formic acid and alcohol, and the alcohol drunk 1 4 is oxidized to acetaldehyde in peroxisomes.

Hello, the main function of catalase is to remove reactive oxygen species from plants, and the pathways for plants to produce reactive oxygen species are 1The excited state of the chloroplast of photosynthesis has not had time to quench, 2Adversity Stress, 3

Plant senescence. Therefore, catalase is involved in photoprotection as well as resistance to adversity and the process of slowing down aging.

Hydrogen peroxide has a strong oxidizing effect on organic matter, and test strips can be prepared accordingly, generally with organic dyes oxidative fading or discoloration, such as methyl orange test strips. However, there are many interfering factors, such as oxygen and other oxidizing agents.

Horseradish peroxidase (HRP) is commonly used in the spike oxidase method, and due to the singularity of the enzyme reaction, there are few interfering factors. The substrate of HRP is hydrogen peroxide, and there are several hydrogen donors during the catalytic reaction: (1) o-phenylenediamine (OPD), and the product is orange and can be identified by the naked eye.

2) Anisamine (OD), the product is orange and the color is relatively stable; (3) 5-aminosalicylic acid (5 as): the product is dark brown and has poor sensitivity; (4) The o-toluidine (OT) product of rock lead is blue jujube, unstable and acid-resistant, but the reaction is fast and the color is obvious.

Hydrogen peroxide is an enzyme that catalyzes the decomposition of hydrogen peroxide into oxygen and water, which is generally said to have a protective and detoxifying effect on the human body. Catalase is used for disinfection and cleansing of traumatic injuries, and it is very useful for Zheng Duan.

Catalase (CAT), an enzyme that catalyzes the breakdown of hydrogen peroxide into oxygen and water, is present in the peroxisomes of cells. Hydrogen peroxide trembling enzyme is the hallmark enzyme of peroxisomes, accounting for about 40% of the total peroxisome enzymes.

Catalase is present in various tissues of all known animals, especially in the liver at high concentrations. Catalase is used in the food industry to remove hydrogen peroxide from milk used to make milk holes. Catalase is also used in food packaging to prevent food from being oxidized.

Catalase catalizes the decomposition of hydrogen peroxide (hydrogen peroxide) into oxygen and water through a redox reaction.

According to its reaction characteristics, catalase can be used for the production of sodium gluconate by double enzymatic method (glucose oxidase and catalase) to improve the production efficiency of sodium gluconate; Such as: Xiasheng liquid food peroxide Bihe hydrogenase FDY-3505

It can also be used to treat sewage containing hydrogen peroxide, which can effectively degrade hydrogen peroxide and make the sewage meet the standard of discharge or reuse; Such as: Xiasheng liquid industrial catalase 400,000 enzyme live GDY-2001

At the same time, it can also be used in food processing to remove hydrogen peroxide residues in food disinfectants. For example, Xiasheng liquid food-grade catalase 400,000 enzyme active FDY-2213
