Background:
Lipid is a class of biological molecules defined by low solubility in water and high solubility
in non-polar solvents. Unlike other biomolecules, lipids do not have a common structural feature
that serves as the basis for defining such compounds but they can be grouped based on their
solubility in nonpolar organic solvents such as hexane, petroleum ether, and dichloromethane.
Lipids has a wide array of functions, it could be used for storage of energy – lipids represent highly
reduced forms of carbon and, upon oxidation in metabolism, yield large amounts of energy,
making them molecules of choice for metabolic energy storage. It is also a membrane
components which provide insoluble compartments in the cell that contains aqueous solutions.
Lipids can also serve as chemical messengers. Triacylglycerols are considered the energy providing lipid, it is more efficient than other energy storage in biological systems. It is composed of three fatty acid molecules attached to a glycerol backbone through ester bonds. Aside from providing energy, triacylglycerols are derivatives of cell membrane lipids (phosphoacylglycerols and sphingolipids), as well as the waxes found in the leaves of plants in produced by some animals. It is then important for humans and other organisms to receive an adequate amount of triacylglycerols in the diet. Dietary sources of lipids come from various plant and animal sources. Oils are of plant
origin and are liquid at room temperature. Fats, on the other hand, are of animal origin and are
solid to semi-solid at room temperature. This occurs due to the degree of unsaturation found in
the fatty acid components.
