Extended data:
1, phosphorus and calcium are important components of bones and teeth, and they are indispensable nutrients to promote calcification of bones and teeth. Some babies often suffer from rickets or rickets because of lack of calcium and phosphorus. The main component of bones and teeth is called apatite, which is composed of phosphorus and calcium.
When people reach adulthood, although the bones have stopped growing, the calcium and phosphorus in them are still constantly updated, about 20% every year. In other words, it is updated every five years. However, once the teeth grow out, they will lose the ability to repair themselves. If children lack calcium when they grow teeth, their teeth are easily damaged.
2. Maintain the balance of ATP metabolism in the body.
3. Phosphorus is one of the basic components of nucleic acid, and nucleotide is the basic unit of ribonucleic acid (RNA) and deoxyribonucleic acid (DNA), which is an important substance for transmitting information and regulating cell metabolism in life.
4. Phosphorus can also make the heart beat regularly, maintain the normal function of the kidney and transmit important substances of nerve stimulation. Without phosphorus, nicotinic acid (also known as vitamin B3) cannot be absorbed, and the normal function of phosphorus needs vitamin D (vitamin food) and calcium (calcium food) to maintain.
