_{4. Dipalmitoylphosphatidycholine}

_{5. corticosterone}

_{6. glucocerebroside}

Answer 1

Example	Class of lipids
Estradiol	steroid
Linoleic acid	fats and oil
Glyceryl tristearate	waxes
Dipalmitoylphosphatidylcholine	phospholipids
Corticosterone	steroid
Glucocerbroside	glycolipids

Lipids are biomacromolecules. They are polymers of glycerides. Glycerides are made up of glycerol and fatty acids. The synthesis of glyceride is called as esterification reaction which is a dehydration or condensation reaction. One molecule of glycerol can form ester bond with one molecule of fatty acid to form monoglyceride or two molecules of fatty acids to form diglycerides or three molecules of fatty acids to form triglyceride. These are branched or unbranched linear molecules of lipids. Ringed molecules of lipids are derivatives of sterols.
