monohydrogenfosfat

Monohydrogenfosfat, also known as hydrogen phosphate or dibasic phosphate, is an inorganic chemical compound with the formula HPO4^2-. It is an anion that exists in equilibrium with other phosphate species in aqueous solutions, depending on the pH. The monohydrogenphosphate ion is one of the three main species of phosphoric acid, the others being dihydrogenphosphate (H2PO4^-) and phosphate (PO4^3-).

In its salt form, monohydrogenfosfat is found in various compounds, such as disodium monohydrogenphosphate (Na2HPO4) and dipotassium monohydrogenphosphate (K2HPO4). These salts are often used as buffering agents, emulsifiers, and leavening agents in food products. For example, disodium monohydrogenphosphate is commonly found in processed cheeses to prevent oil separation and improve texture.

Monohydrogenfosfat plays a crucial role in biological systems. It is a component of the phosphate buffer system in blood, which helps maintain the pH balance of the body. In cellular metabolism, it is involved in energy transfer through molecules like adenosine triphosphate (ATP). Phosphate ions, including monohydrogenfosfat, are essential for bone formation and are also integral parts of DNA and RNA. The body tightly regulates phosphate levels to ensure proper physiological function.
