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 functional groups are on the same side of the carbon chain whereas in trans  configuration, the functional groups are on the opposingside of the chain.
