Answer 2

Lipids are a heterogeneous group of organic compounds that are important con­stituents of plant and animal tissues. They are arbitrarily classed together according to their solubility in organic solvent such as benzene, ether, chloroform, carbon terachloride (the so-called fat solvents) and their insolu­bility in water. Their solubility properties are a function of their alkane-like structures.

Unlike polysaccharides and proteins, lipids are not polymers—they lack a repea­ting momomeric unit. However, like carbo­hydrates, they can be classified according to their hydrolysis products and according to similarities in their molecular structures. Three major subclasses are recognised:

1. Simple lipids:

(a) Fats and oils which yield fatty acids and glycerol upon hydrolysis.

(b) Waxes, which yield fatty acids and long-chain alcohols upon hydrolysis.

2. Compound lipids:

(a) Phospholipids, which yield fatty acids, glycerol, phosphoric acid and a nitrogen-containing alcohol upon hydrolysis.

(b) Glycolipids, which yield fatty acids, sphingosine or glycerol, and a carbo­hydrate upon hydrolysis.

(c) Sphingolipids, which yield fatty acids, sphingosine, phosphoric acid, and an alcohol component upon hydrolysis.

3. Steroids:

Compounds containing a phenanthrene structure that are quite different from lipids made up of fatty acids.
