Phosphate is a compound that exists in the body containing phosphorus.

Phosphorus is one of the most abundant elements in the body, usually existing in the form of phosphate compounds. Phosphate plays an important role in the formation of some organic compounds such as nucleic acids, cell membrane phospholipids, participating in aerobic and anaerobic energy metabolism, and providing oxygen to tissues. Therefore, when there are disorders in the concentration of phosphate in the blood, it can cause harmful or pathological reactions in the human body.
