The fatty acid chain of the lipids is often referred to as a hydrocarbon chain. discuss with your group why the chain is given this name and write a one-sentence definition for a hydrocarbon.

               Hydrocarbons are those compounds which are entirely made up of only carbon and hydrogen atoms.

Explanation:

In biochemistry, Lipids are the macromolecules that contains a long chain hydrophobic (non polar) hydrocarbon chain and helps in building and functioning of the living cells. The examples of Lipids are waxes, oils, fats, harmones, non-protein membranes and certain vitamins.

Fatty Acids belong to the class of organic compounds called as carboxylic acids containing a long chain of hydrocarbons and a carboxylic functional group (-COOH) at one end.

Hydrocarbons: In organic chemistry hydrocarbons are those compounds which are entirely made up of only carbon and hydrogen atoms. As the bonding between H and C atoms is non-polar therefore, the hydrocarbons are insoluble in polar solvents like water hence, are designated as hydrophobic (water fearing).
