Chemical properties. The phosphate ion has a molar mass of 94.97 g/mol, and consists of a central phosphorus atom surrounded by four oxygen atoms in a tetrahedral arrangement. It is the conjugate base of the hydrogen phosphate ion H(PO 4) 2−, which in turn is the conjugate base of the dihydrogen phosphate ion H 2 (PO 4) −, which in turn is the conjugate base of orthophosphoric acid, H

concentration of 238U in sedimentary phosphate deposits is 1500 Bq/kg [3, 4]. Uranium content of fertilizers can vary according to their phosphate content.

The concentration of phosphate inside the cytosol is already greater than the concentration of phosphate in the surrounding fluid, yet, the cell still want to move more phosphate into the cell. To do this, energy is needed to move the phosphate ions against the concentration gradient, so the type of transportation requires is ACTIVE TRANSPORT.

Phosphorus is the second most abundant mineral in the body, behind calcium. In your body it is primarily found in the form of phosphate. Every cell in your body needs phosphorus to function properly, but 85 percent of the phosphorus is stored in your bones. While phosphorus is an essential nutrient, getting too much can be bad for your health.
