inorganic phosphate
Noun 1. A salt of phosphoric acid: A chemical compound containing the phosphate ion (PO₄³⁻), derived from phosphoric acid (H₃PO₄). These compounds are essential in biological systems for energy transfer (e.g., ATP) and as a structural component of bones and teeth.
This is a scientific term used primarily in chemistry, biochemistry, and biology. - It refers to ionic compounds where the phosphate anion is combined with cations like sodium, calcium, or potassium. - In biological contexts, it is often simply called "phosphate" when discussing its role in cellular processes.
- In Biochemistry: "Adenosine triphosphate (ATP) stores energy in its bonds between adenosine and inorganic phosphate groups."
- In Agriculture: "Fertilizers often contain inorganic phosphate to supplement soil nutrients for plant growth."
- In Environmental Science: "Excess inorganic phosphate in waterways can lead to algal blooms."
- "Free inorganic phosphate" (Pi): Often used in biochemistry to denote the phosphate ion (PO₄³⁻) that is not bound to another organic molecule, making it available for metabolic reactions.
- "Inorganic phosphate concentration": A measured parameter in laboratory studies of cellular metabolism and mineral balance.
- Phosphate (n): A common short form for inorganic phosphate, especially in biological contexts.
- Orthophosphate (n): A more specific chemical term synonymous with inorganic phosphate, referring to the simplest phosphate ion (PO₄³⁻).
- Phosphate ion salt
- Orthophosphate
The term "inorganic" distinguishes these compounds from organic phosphates, where the phosphate group is bound to a carbon-containing (organic) molecule, such as in DNA or phospholipids. Therefore, "inorganic phosphate" specifically denotes the mineral form.
