Used enzyme
What exactly is an enzyme? The most essential component of enzyme is protein, and protein is a biocatalyst produced by living cells in organisms. It can efficiently catalyze various biochemical reactions under very mild conditions in the body. Different enzymes are related to various tasks, such as digestion and metabolism, and correcting hormone functions such as insulin and glucagon. Many enzymes help break down food molecules and compounds, such as lactose and protein, to help absorb these nutrients correctly. Don't underestimate this substance. There are a large number of enzymes in human body, which have complex structures and various types. Up to now, more than 5000 species (diversity) have been found, which dominate the metabolism, nutrition and energy conversion of organisms. Many catalytic processes closely related to life processes are enzymatic reactions.

Chemical reaction of enzyme
The human body and other living things must carry out thousands of different chemical reactions. Digestion, absorption, transportation, synthesis, secretion, exercise, reproduction (commonly known as substance metabolism) and other activities are based on chemical reactions. Most of these reactions are slow, and enzymes accelerate these reactions, so that all kinds of activities on which life depends can be carried out in time. Most of these reactions are carried out in cells; Each reaction is catalyzed by a different enzyme; Cells contain thousands of enzymes, which are isolated in various cells and systematically catalyze life-threatening reactions.
Take the starch you eat every day as an example. Starch is digested in digestive tract, hydrolyzed by amylase into glucose, and glucose enters cells under the catalysis of enzyme. The metabolism of glucose in cells is a series of enzyme-catalyzed reactions, which oxidizes glucose into carbon dioxide and water and supplies energy, and also transforms it into other substances such as fat. Compared with in vitro combustion, the products of glucose oxidation in vivo are both carbon dioxide and water, and both of them release energy at the same time. However, in vivo oxidation is carried out under mild conditions such as room temperature due to the catalysis of enzymes. After many steps, it gradually releases energy that is convenient to use, which is very different from in vitro combustion.
Constitute and repair tissue
Modern medical research shows that the human body needs no less than 100 kinds of protein, and some protein can be synthesized and manufactured by itself; Some cannot be synthesized and must be absorbed by the outside world. Protein is the substance that constructs and repairs various tissues and cells of human body, such as human nerves, muscles, internal organs, blood and bones. Protein is the foundation of all living things. With the growth of age, protein will continue to decompose, so most elderly people are thinner. Protein is mainly digested and absorbed by human small intestine. The function and decomposition of the stomach, the source of protein is directly proportional to food and itself, and protein is absorbed and excreted every day. Therefore, the human body must consume a certain amount of protein every day as a material for building and repairing tissues.
The enzymes produced in a person's life are limited. The older you get, the more your body depends on the enzymes in food. If we don't eat enough enzymes in food, our body will be forced to consume metabolic enzymes in other parts of the body. These enzymes are needed for the normal operation of body organs and systems, so the more we consume the body's natural enzyme reserves, the greater the harm to health. The amount of these digestive enzymes will decrease after aging, but they can be supplemented by health products and diet. Enzyme is an essential substance for life, and many diseases are caused by the lack or imbalance of enzyme.
It can be seen that enzymes play an unparalleled role in the human body. Only when enzymes exist can human beings have a healthy body and life.
With the improvement of living standards, people pay more and more attention to health problems. Enzymes play an important role in human metabolism and are closely related to human health. In a sense, understanding enzymes means understanding ourselves.
