Enzymes, formerly known as enzymes are complex proteins with catalytic effects, and this catalytic ability is called enzyme activity. Almost all chemical changes in living organisms are catalyzed by enzymes. The action of enzymes is highly specialized, and the catalytic efficiency of enzymes is very high. One enzyme molecule can catalyze the conversion of hundreds to millions of substrate molecules in less than a minute. Enzymes are usually named according to their substrates or the nature of their action. For example, amylase acts on starch, rennet causes coagulation of milk, and glucose oxidase catalyzes the oxidation of glucose. Enzymes are of great significance in the treatment and diagnosis of diseases, in the understanding of the nature of life phenomena, and in industrial and agricultural production.

Coenzymes are non-protein small molecule organic substances necessary for enzyme catalysis, and many coenzymes are derivatives of vitamins, such as vitamin Bl, which is involved in some physiological functions of the body in the form of coenzymes.　　Pine pollen naturally contains nearly 100 kinds of enzymes needed by human body, which can promote human gastrointestinal peristalsis, enhance appetite, regulate human digestive function, promote digestion and absorption, and have a good repairing effect on gastric ulcers, duodenal ulcers, atrophic gastritis, etc., and regulate human immune system, endocrine system, etc., to play its unique role, a variety of natural enzymes and coenzymes are important components of pine pollen, which are outstanding features superior to other health food.
