Introduction to biological enzymes and their properties

Date of issue:2019-07-10 Authors: Click:

The biological enzyme is abbreviated as <enzyme>, and the biological enzyme produced in the industry is also called an enzyme preparation.

First, what is an enzyme? An enzyme is a catalytic, special protein produced by a living organism and composed of 20 amino acids. It is also called a biocatalyst. The main feature of life activities is metabolism, and various chemical reactions in metabolism are carried out under the action of enzymes. Enzymes are substances that promote metabolism. If there is no enzyme, there is no metabolism, so there is no life phenomenon.

             

             

Second, the five characteristics of the enzyme (five characteristics):

1. Excessive effectiveness of enzyme catalysis. We know that the chemical reaction in the organism is extremely rapid, which shows that the catalytic effect of the enzyme is effective. The catalytic effect of the enzyme is 100,000 times to a million times higher than that of the general chemical catalyst. This means that only a small amount of enzyme is needed to complete the catalysis. For example, Danny Yue leather enzyme DENIE-LIME388-2P (L) is used as a leather liming depilatory alkaline protease in the production of only 0.15% -0.3% (by weight of leather).

2. The specificity of enzyme catalysis. That is, an enzyme preparation acts only on a specific substance. The substance that the enzyme can act on is academically called "substrate". The relationship between the substrate and the enzyme preparation is like the relationship between the lock and the key. When a key is opened, a lock can only be opened. This is the normal relationship. . The specificity of the enzyme substrate determines the safety of the enzyme preparation involved in the reaction. In addition to the need to pay attention to the survival requirements of the enzyme preparation, you do not have to worry about the enzyme preparation reacting with other chemicals. You say, if the enzyme is added to a detergent with various chemicals and buffers, will the enzyme react with other chemicals? This specificity tells you: No, it won’t Reaction, you can safely add enzyme preparations. The specificity of the enzyme preparation against the substrate, that is, the cellulase acts only on the plant cellulose, and it does not work on proteins, starches, and the like. Protease is able to hydrolyze animal and vegetable proteins and does not work on plant fibers. Amylase only hydrolyzes starch and does not work on cellulose and fat. Because it is specific, it is safe.

3. The catalytic conditions of the biological enzyme are alleviated. Since the enzymes are obtained from organisms, their catalysis is carried out in an environment close to the temperature of the object and near neutral. This feature provides a bright prospect for the application of biological enzymes in dyeing and finishing, making some difficult processing into reality.

4. Controllability of enzyme catalytic activity. Including the choice of enzymes, the amount of enzymes, the pH adjustment of enzymes, the time of enzyme action, etc. can be controlled by humans, thus avoiding waste and loss. Textile washing industry, leather washing industry, paper bleaching and detergent plus enzyme samples can be immediately seen, quickly know how to use it, how to use and how much; and the breeding industry sample cycle is longer, chicken has 40 - For 50 days, pigs get 4-6 months. However, companies that have used biological enzymes do not have to try it. If they know well, they can order directly.

5. Green and environmental protection. Because the enzyme is taken from plants and animals and micro-organisms, the enzyme has a non-toxic nature and is a green environmentally-friendly fine chemical. This green nature has considerable economic and social benefits in production. If the production conditions are improved, the amount of chemical agents is reduced, and the wastewater discharge is reduced, environmental pollution is reduced, and the production cost is also reduced. The bio-enzymes we produce do not have the pressure of sewage discharge, and there is no concern about human poisoning; this green environmental advantage can give our producers and users full confidence and confidence: we sell Danny's enzyme preparation products is to give The company sent money and contributed to the green environment.
