(a)
Interpretation:
The relation between all- trans- retinal and 11- cis- retinal should be determined.
Concept Introduction:
If two compounds have the same molecular formula but different chemical structures, then such phenomenon is termed as isomerism. Moreover, such compounds are termed as the isomers of each other. Isomerism is broadly divided into two broad categories, constitutional isomerism, and stereoisomers.
(b)
Interpretation:
The relation between all- trans- retinal and vitamin A should be determined.
