LIPIDS

  1. Term given by Bloor.
  2. Lipids do not form polymers in nature except cutin (polymere of fatty acids).
  3. Most lipids are formed of fatty acids & alcohol.
  4. Ester bond is formed between them.
  5. In each fatty acid 1 carboxyle group is present.
  6. Lipids are formed of Carbon, Hydrogen and often Oxygen where Oxygen content is very small as compared to other two elements.
  7. Some lipids also contain small amounts of Phosphorus, Nitrogen are rarely Sulphur.
  8. Lipids require more oxygen for their complete oxidation as compared to carbohydrates.
  9. On their oxidation maximum water is released, so hump of camel is made up of fat.
  10. They contain and liberate almost double the energy of carbohydrates.
  11. Lipids are insoluble in water but soluble in organic solvent, e.g. alcohol, acetone, ethers, carbon tetrachloride.
  12. Lipids are micromolecules.
  13. When in solution of glycerophosphide weak sound waves are passed, little lipid is dissolved in sol & liposome is formed.
