This chapter investigates the role of lipids in biological systems, including
their structural variety and significance in liposome formation and function. It focuses
on a variety of lipids, including fats, oils, sterols, glycerophospholipids, and sphingolipids, with a particular emphasis on phospholipids, sphingolipids, and cholesterol,
all of which play important roles in liposome structure. The chapter investigates the
structural features of these lipids, their distinct contributions to cellular membranes,
and their effects on biological processes. The involvement of cholesterol in lipid
bilayer stabilization, the amphiphilic character of phospholipids in membrane synthesis, and the structural importance of sphingolipids in membrane integrity are all
highlighted.
Keywords: Lipids, cholesterol, phospholipids, glycerophospholipids, fatty acids, sphingomyelin.
