What are the three types of polyunsaturated compounds? give examples of all three. 10 page

Polyunsaturated compounds or the polyunsaturated fatty acids are the type of unsaturated fatty acids containing two or more than two carbon-carbon double bonds.

They can be classified into three groups on the basis of their chemical structure:

1. Methylene-interrupted polyenes: contain more than one cis double bonds which are separated by a methylene group. Example: Linoleic acid

2. Conjugated fatty acids: contain at least one double pair which is separated by a single bond. Example: Punicic acid

3. Other polyunsaturated fatty acids. Example: Pinolenic acid

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
