Abstract
Lipids are water-insoluble hydrocarbon derivatives with many physiological
functions. They are the structural components of membranes. The long chain fatty acid
chains of lipids can be broken down to serve as energy fuels, as well as they play a role
in intracellular signaling. The entire composition of lipid molecules in a cell constitutes
its lipidome. In this chapter, we will discuss the different roles played by lipids by their
chemical properties in detail.
