Abstract
The most important components that make up cell membranes are various types of lipids. By cataloging lipid structures (referred to as lipidomics), eukaryotic cells have been found to invest substantial resources in generating various types of lipids. Cells use about 5 % of their genes to encode for the synthesis of these lipids. Lipids perform a few general functions. First of all, lipids are used for energy storage, principally as triacylglycerol and steryl esters, in lipid droplets. The matrix of cellular membranes is formed by polar lipids, which consist of a hydrophobic and a hydrophilic portion. Furthermore, lipids act as first and second messengers in signal transduction and molecular recognition processes.
