NMN belongs to the category of vitamin B derivatives, and its functions are mainly reflected through NAD·, which is widely involved in a number of biochemical reactions in the human body and is closely related to immunity and metabolism.
NAD+also known as coenzyme I, full name nicotinamide adenosinate dinucleotide, it is widely distributed in human cells, involved in thousands of biocatalytic reactions, is an essential coenzyme in the human body. NAD + there are mainly the following reactions:
- The Rirtuins pathway, which is consumed to turn on longevity genes;
- PARPs pathway for DNA repair;
- CD38 pathway, used for calcium signaling;
- NADP(H) synthesis, etc.
With the increase of age, the content of NAD +in the human body continues to decline, resulting in a decline in physical function, and aging brings a series of diseases. NMN can activate seven known anti-aging proteins SIRtuins1-7, delaying the physiological aging of body organs caused by aging.
