Urgently, a biological problem, the relationship between catalase and vitamin C, there will be a lot

Not sure what aspect you want.

They are both important antioxidants in the body, which is probably the common denominator.

Catalase achieves antioxidant by catalytic decomposition of hydrogen peroxide, and vitamin C reduces various oxygen radicals through strong reducibility. So as to reduce the harm of oxidation groups to the body and delay cell aging.

Catalase is present in all known animal tissues, especially in the liver at high concentrations, and as an antioxidant enzyme, the enzyme needs a free sulfhydryl group (-sh) to remain active. VC can reduce the disulfide bond (-S-S) to -SH, thereby increasing the activity of related enzymes and exerting antioxidant effects.

Catalase is present in peroxides in red blood cells and some tissues, and its main role is to catalyze the decomposition of H2O2 into H2O and O2, so that H2O2 will not react with O2 under the action of iron chelate to form very harmful -OH

Vitamin C (ascorbic acid), also known as L-ascorbic acid, is a water-soluble vitamin. Vitamin C in food is absorbed by the upper part of the body's small intestine. Once absorbed, it is distributed to all water-soluble structures in the body, vitamin C can be oxidized or reduced in the body, so it can be used as a hydrogen donor, and as a hydrogen acceptor, playing an important role in the redox process in the body.

Hydrogen peroxide and vitamin C are both important antioxidants in living organisms.

If you leave it for a long time, it will spoil.

Yes, vitamin C is a reducing substance, while hydrogen peroxide is highly oxidizing, so putting these two substances together will cause a rapid redox reaction.

Catalase, an enzyme that catalyzes the decomposition of hydrogen peroxide into oxygen and water, is found in peroxides in cells. Although the complete catalytic mechanism of catalase is not fully understood, its catalytic process is thought to be a two-step process:

h2o2 + fe(iii)-e → h2o + o=fe(iv)-e(.+

h2o2 + o=fe(iv)-e(.+h2o + fe(iii)-e + o2[12]

On the whole, Fe is the catalyst, and hydrogen peroxide itself is both oxidized and reduced. This reaction does not mention the reductive effects of VC itself, and it is estimated that it was not directly involved in the reaction.

Simply putting hydrogen peroxide and VC together certainly has a reaction, but the biological problem cannot be viewed from a chemical point of view alone. Catalase does not seem to be the type of enzyme that VC can affect activity – VC maintains the activity of thiolases, and you can check the literature to see what factors affect catalase activity.

Vitamin C does not have the effect of promoting enzyme activity
