What is Biological enzymes and its application?

Biological enzymes are organic substances with catalytic effects produced by living cells, most of which are proteins, and a very small part of them are RNA. Its manufacturing and application fields are gradually expanding, and its application in the textile industry is becoming more and more mature. From the past mainly used for the desizing of cotton fabrics and the degumming of silk, it is now widely used in various fields of textile dyeing and finishing, which embodies biological enzymes. Superiority in the dyeing and finishing industry. Enzymes also made important breakthroughs in the field of human skin care in 2016 and have entered the stage of clinical application.

Biological enzyme is a non-toxic, environmentally friendly biological catalyst, and its chemical nature is protein. The production and application of enzymes has a history of more than 80 years at home and abroad. In the 1980s, bioengineering, as an emerging high-tech technology, has developed rapidly in my country. The manufacturing and application fields of enzymes have gradually expanded. Enzymes are used in the textile industry. The application of the product is also becoming more and more mature. From the past mainly used for the desizing of cotton fabrics and the degumming of silk, it is now widely used in various fields of textile dyeing and finishing, which reflects the superiority of biological enzymes in the dyeing and finishing industry. Now the enzyme treatment process has been recognized as a green production process that meets environmental protection requirements. It not only improves the wearability of textiles, but also because it is non-toxic and harmless, with a small amount, biodegradable wastewater, and pollution-free. Conducive to the protection of ecological and environmental protection. Biological enzymes are widely used in textiles, petroleum, papermaking, food processing, pollution control and other fields. At the same time, biological enzymes are also used in the field of indoor decoration pollution, through catalysis, swallowing, decomposition and other methods to eliminate indoor decoration odors, formaldehyde, etc. Pollution.

The difference between enzyme protein and other proteins is that all enzymes have active centers. Enzymes can be divided into quaternary structures: the primary structure is the sequence of amino acids; the secondary structure is the planar spatial conformation of the peptide chain; the tertiary structure is the three-dimensional spatial conformation of the peptide chain; the quaternary structure is the peptide chain with non-covalent bonds Combine each other to form a complete protein molecule. It is the primary structure of the enzyme that really plays a decisive role, and its change will change the nature of the enzyme (inactivation or denaturation). The mechanism of enzyme action is more recognized by Koshland's "inducible fit" theory, its main content is: when the substrate is bound to the active site of the enzyme, there is a change in the conformation of the enzyme. The correct orientation of the catalytic group is necessary for catalysis. The substrate induces a change in the conformation of the enzyme protein, leading to the correct positioning of the catalytic group and the binding of the substrate to the active site of the enzyme, and heavy metal ions will bind to the active site to inactivate the enzyme.
