The term "enzyme" is actually misused, and the proper noun is "enzyme". They are all English enzyme translations. Enzymes in the mainland are uniformly translated as "enzymes", and enzymes in Hong Kong and Taiwan are translated as "enzymes". Therefore, in all regular biochemistry textbooks or medical textbooks on the mainland, there is only "enzyme", and the term "enzyme" is basically not found.

　　 enzymes (ie enzymes) are catalysts for chemical reactions. What is a catalyst? Anyone who has studied middle school chemistry knows that manganese dioxide is used as a catalyst in the experiment of using KClO3 to produce oxygen. Manganese dioxide can accelerate the rate of biochemical reactions (improve the efficiency of oxygen production), but does not change the direction and products of the reaction. Enzymes (ie enzymes) are catalysts in living organisms, and different enzymes catalyze different biochemical reactions. For example, during the oxidation of glucose to CO2, H2O and energy, the catalysis of various enzymes such as "pyruvate dehydrogenase" and "α-ketoglutarate dehydrogenase" is required.

　　 Unlike manganese dioxide, the enzymes (ie enzymes) in the organism are all organic macromolecular substances whose nature is protein. Because of this, after oral administration of enzymes (ie enzymes), they cannot be directly absorbed at all. They must be digested and broken down into amino acids before they can be absorbed into the bloodstream. However, once the enzyme (ie enzyme) is digested and broken down into amino acids, it loses its catalytic effect. Enzymes (ie enzymes) cannot enter the blood in an active form, so they cannot play a role in blood pressure, blood sugar, blood lipids, skin, bones...

　　 So, are oral enzymes (ie enzymes) useless? Of course not, there are several enzymes (ie enzymes) that can still play a role. Such as papain (from papaya), bromelain (from pineapple) and complex enzymes (from bacteria) in yeast tablets. The common feature of these enzymes is that they function in the gastrointestinal tract (help digest food) and do not need (or are impossible) to enter the bloodstream.

　　As far as existing knowledge is concerned, oral enzymes (ie enzymes), whether it comes from natural foods such as papaya and pineapple, or from the bacteria and bacteria, or from bioengineering technology, are limited to the stomach The intestine plays a role. Its role is mainly to promote digestion. Therefore, oral enzymes (ie enzymes) may be helpful for those with poor gastrointestinal digestion. For those with normal gastrointestinal digestive function, oral enzymes (ie enzymes) have no additional benefits.
