Detailed explanation-1: -Phosphorus plays a major role in the structural framework of DNA and RNA. Living cells use phosphate to transport cellular energy with adenosine triphosphate (ATP), necessary for every cellular process that uses energy. ATP is also important for phosphorylation, a key regulatory event in cells.
Detailed explanation-2: -Phosphorus is needed for the growth, maintenance, and repair of all tissues and cells, and for the production of the genetic building blocks, DNA and RNA.
Detailed explanation-3: -Phosphorus, the 11th most common element on earth, is fundamental to all living things. It is essential for the creation of DNA, cell membranes, and for bone and teeth formation in humans.
Detailed explanation-4: -Phosphorus is a component of bones, teeth, DNA, and RNA [1]. In the form of phospholipids, phosphorus is also a component of cell membrane structure and of the body’s key energy source, ATP.
