Question
Chapter 12, Problem 12.71P
Interpretation Introduction
Interpretation:
Carbon-carbon double bonds in lycopene having the possibility for cis-trans isomerism should be determined.
Concept Introduction:
Lycopene is a bright red pigment and phytochemical found in red fruits and vegetables like tomatoes, carrots,etc. but not in cherries or strawberries. It is a free radical fighting antioxidant,and it helps in the protection against cancer.
Cis-trans isomerism is also known as configurational isomerism. In cis configuration, the

a
In omega-3 fatty acids, the last carbon of the last double bond of the hydrocarbon chain ends three carbons from the methyl terminal end of the chain. The last carbon of the chain is called the omega carbon, hence, the designation omega-3. Eicosapentaenoic acid is a common omega-3 fatty acid found in cold water fatty fish and health food supplements.
How many cis-trans isomers are possible for this fatty acid?
cis-trans isomers
