PO4 Meaning: Definition, Examples, and Translations
⚗️
PO4
[piː oʊ fɔːr ]
Definition
chemical compound
PO4, or phosphate, is a chemical compound that consists of one phosphorus atom bonded to four oxygen atoms. It plays a critical role in biological systems, particularly in energy transfer and metabolism, as it is a component of ATP (adenosine triphosphate). Phosphate is also significant in agriculture as a fertilizer ingredient to enhance plant growth.
Synonyms
phosphate, phosphoric acid, tetraphosphate.
Examples of usage
- The soil lacked sufficient PO4 for optimal crop growth.
- In biochemistry, PO4 is vital for cellular energy production.
- Excessive PO4 runoff can lead to water pollution.
- Many foods contain natural PO4, essential for nutrition.

Origin of 'PO4'
Main points about word origin
- The term 'phosphate' comes from 'phosphor' which is based on the Greek word for 'light-bearer', referring to phosphorus's bright glow.
- The 'P' stands for phosphorus, which is found in the word 'phosphorescent', linking both to light and energy.
The term 'phosphate' originates from the Greek word 'phosphoros,' which means 'light-bringer,' referring to phosphorus discovered in 1669 by Hennig Brandt. The term became prevalent in the 18th century, primarily linked with the discovery of phosphoric, phosphoric acid, and phosphate minerals. In the 19th century, phosphate's importance grew with its utilization in fertilizers and detergents. With the advent of modern chemistry, the understanding of phosphate’s role in biological systems, such as DNA and RNA synthesis, expanded. Today, phosphates are recognized as essential nutrients for plants and are integral to sustainable agriculture.
