A phosphate group
In a phospholipid molecule, a phosphate group usually binds to a charged organic molecule, such as choline or the amino acid serine.
A phosphate group is a functional group that is made up of one atom of phosphorus that is covalently attached to four oxygen residues, and with a net negative charge. Phosphate groups are reactive molecules that easily form phophoester bonds when they interact with hydroxyl groups. Phosphates can form phospholipids and each phospholipid molecule contain a lipid molecule and a phosphate group .
Answer:
phosphate group
Explanation:
Phospholipid molecules also known as phospholipids are molecules composed of a phospho-group attached to other organic molecules such as amino acids, glycerals, among others. The phosphate group provides energy to the molecule, making it essential for all metabolic processes in the body, as well as being essential for cell survival and development. Lecithin (phosphatidylcholine) is one of the major phospholipid molecules, being the major component of the cell membrane and lipoproteins.
