Lipids are hydrophobic or amphipathic small molecules that may originate entirely or in part by carbanion-based condensations of thioesters (fatty acids, polyketides, etc.) and/or by carbocation-based condensations of isoprene units .

Examples of common lipids include butter, vegetable oil, cholesterol and other steroids, waxes, phospholipids, and fat-soluble vitamins. The common characteristic of all of these compounds is that they are essentially insoluble in water yet soluble in one or more organic solvents. . DR. SHAIMAA MUNTHER. LIPIDS CHEMISTRY . The term “lipids” applies to a class of compounds that are soluble in organic solvents (e.g. alcohol and chloroform) and insoluble in water. . Lipids are essential components of every living cell. .
