Function of Lipids
In our bodies, lipids store energy and create the cell membrane of our cells. This helps maintain homeostasis by regulating what goes inside a cell, and controlling body temperature.
Lipids can also help cushion and protect vital organs, and communicate with other cells.
The head of a fatty acid is a carboxyl, which repels water. This helps lipids perform their function because in the cell membrane, the heads of the fatty acids repel water, so the cell is not flooded with water.
The structural shape of a lipid is a long chain. These chains have lots of bonds in their formation, so energy that needs to be stored can be kept in the bonds.
