Phosphate metabolism refers to the processes by which the body utilizes and regulates phosphate, an essential mineral found in bones and teeth. Phosphate plays a crucial role in energy production, DNA synthesis, and cellular signaling. It is primarily absorbed from dietary sources, such as meat, dairy, and grains, and is regulated by hormones like parathyroid hormone and calcitriol. The kidneys are vital in maintaining phosphate balance, filtering excess phosphate from the blood and excreting it in urine. Imbalances in phosphate levels can lead to health issues, including osteoporosis or kidney disease. Proper phosphate metabolism is essential for overall health and well-being.
