Linoleic acid and -linolenic acid are two naturally occurring us-saturated fatty acids that are components of fats.

Linoleic acid and α-linolenic acid are two naturally occurring us-saturated fatty acids that are components of fats. Explain how many cis-trans isomers exist for each of these of these fatty acids. Interestingly, only the all-cis isomers of each occur naturally. Draw the structure of the naturally occurring stereo isomer of linoleic and α-linolenic acid using skeletal structures.
