Ubidecarenone
Coenzyme Q10 is a kind of small molecule fat soluble quinone organic compound widely existing in animal and plant cells. Its structure is similar to that of vitamin K. It is a strong antioxidant when used alone or in combination with vitamin E. It is necessary to drive the energy generation (ATP) cycle of human body. It has the function of promoting oxidative phosphorylation reaction and protecting the structural integrity of biofilm. Coenzyme Q from different sources has different number of isopentene units in its side chain. Human and mammalian are 10 isopentene units, so it is called coenzyme Q10. Coenzyme Q plays an important role in proton translocation and electron transfer in respiratory chain. It is an activator of cell respiration and metabolism, an important antioxidant and nonspecific immunoenhancer. Modern biological research has found that too much free radicals in the body will lead to the damage of genetic material and cell membrane. The macroscopic manifestations are aging, cancer and other symptoms. The process of scavenging free radicals is also known as "antioxidant". We know that life activities are driven by a variety of enzymes. Enzymes are macromolecular proteins. Some enzymes need the help of some small molecules when they perform their functions. These substances are called coenzymes. Coenzyme Q10 is present in mitochondria of cells. Mitochondria are the places where energy is produced in cells. Many enzymes and other molecules are involved in the process of energy production, and coenzyme Q10 is an indispensable one.

Urokinase
Urokinase (trade name Abbokinase), also called urokinase-type plasminogen activator (uPA), is a serine protease (EC3.4.21.73). It was discovered in 1947 by McFarlane. Urokinase was originally isolated from human urine, but is present in several physiological locations, such as blood stream and the extracellular matrix. The primary physiological substrate is plasminogen, which is an inactive form (zymogen) of the serine protease plasmin. Activation of plasmin triggers a proteolysis cascade that, depending on the physiological environment, participates in thrombolysis orextracellular matrix degradation. This links urokinase to vascular diseases and cancer.

VB1
Vitamin B1, also known as "thiamine" or "thiamine", is one of the B vitamins. It can promote normal glucose metabolism, and it is necessary to maintain the normal function of nerve conduction, heart and gastrointestinal tract. It combines with adenosine triphosphate to form vitamin B1 pyrophosphate (thiamine diphosphate or coenzyme), which is a coenzyme necessary for carbohydrate metabolism. The lack of this coenzyme can cause oxidative metabolism to be blocked and form pyruvate and lactic acid accumulation, which affects the body’s Energy supply. Vitamin B1 can also inhibit the activity of cholinesterase, when it is lacking; cholinesterase activity is enhanced, acetylcholine hydrolysis is accelerated, resulting in nerve impulse conduction obstacles, affecting gastrointestinal and myocardial function. Vitamin B1 is rich in seed husks and germs, such as rice bran, wheat bran, etc.; the content of coarse grains is higher than that in refined rice or white flour. Others such as yeast, lean meat, peanuts, soybeans, liver, whole wheat, fresh vegetables such as cabbage, celery, Chinese medicine parsnip, plantain, and coix seed are all rich in vitamin B1. It can be used as a spice, mainly for the preparation of bitter beverages.
