If a person has low levels of phosphorous in his or her blood, phosphorous may be "stolen" from bones to make it available for cellular molecules. Which molecules require phosphorous as part of their structure?
Phosphorous is required to make two essential molecules in the body- the nuclei acid and the phospholipids.
The nucleic acid contains carbon, hydrogen, oxygen, nitrogen, and phosphorus and is organic compounds that codes for the genetic information in an organism. There are two types of nucleic acid- ribonucleic acids and deoxyribonucleic acids, i.e RNA and DNA respectively. Both of them sugar-phosphate backbone and therefore, phosphorous is essential for the synthesis of nucleic acids in the body.
Phospholipids make up the cell membrane and thus, phosphorous is also essential for their synthesis.
