<u>Answer</u>:
There are a number of lipids that are found in foods and contribute to various functions in the body. Triglycerides are the most common lipid found in food and in the body; they consist of a <u><em>Glycerol</em></u><u> </u>backbone attached to three fatty acids.
Fatty acids are classified based on the degree to which the carbon chain is saturated with <u><em>Hydrogen</em></u>
A fatty acid is <u><em>saturated </em></u>if it contains no carbon-carbon double bonds,   <em><u>polyunsaturated </u></em>if it contains  two or more carbon-carbon double bonds, and<em><u> monounsaturated </u></em>if it has only one carbon-carbon double bond.
The unsaturated fatty acids can exist in one of two structural forms: the <em><u>trans </u></em>form occurs when hydrogens on both carbons forming the double bond lie on opposite sides of that bond.
When hydrogens on an unsaturated fatty acid lie on the same side of the carbon-carbon double bond, a <u><em>cis </em></u>formation exists.
