Extract from the above information

It is a coenzyme that improves the body's metabolism and participates in the metabolism of fat, protein, sugar, nucleic acid and nucleotides in the body. It is also the main source of energy in the body. When energy is needed for absorption, secretion, muscle contraction and biochemical synthesis reactions, adenosine triphosphate is decomposed into adenosine diphosphate and phosphate groups, and energy is released at the same time. Animal experiments can inhibit the slow calcium ion influx of slow-reacting fibers, block or delay the forward conduction in the atrioventricular node reentry pathway, and large doses may also block or delay the forward and reverse conduction of the bypass pathway; in addition, it also has a short-term and strong effect of enhancing the vagus nerve, thereby terminating arrhythmias caused by atrioventricular node reentry and bypass reentry mechanisms.

It must be converted by both the liver and kidneys to become biologically active vitamin D3, which plays a role in regulating calcium and phosphorus metabolism. The biological activity of vitamin D2 is far inferior to that of vitamin D3.

Participates in the regulation of calcium and phosphorus metabolism.

This product is first converted into 5-fluoro-2-deoxyuridine nucleotide in the body, which inhibits thymine nucleotide synthetase, blocking the conversion of deoxyuridine nucleotide into deoxythymine nucleotide, thereby inhibiting DNA biosynthesis. In addition, by preventing uracil and orotic acid from incorporating into RNA, the effect of inhibiting RNA synthesis is achieved. This product is a cell cycle-specific drug that mainly inhibits S-phase cells.
