Phosphate Group Definition
A negative-charged functional group or radical composed primarily of phosphorus connected to four oxygen atoms. The sign PO4– is used to represent it.
The phosphate group plays a variety of roles in living organisms.
To begin with, it is a crucial structural component of the nucleotide, which is the fundamental structural unit of DNA and RNA.
Second, it is a constituent of energy-dense molecules like ATP.
Finally, it is linked to coenzymes involved in anabolic processes, such as NADP/NADPH (such as photosynthesis in plants and lipid synthesis in animals).
In biological membranes, it is also a component of the hydrophilic head of phospholipids.
