Conjugated diene consists of two double bonds that are separated by a single bond, whereas isolated diene also consists of two double bond but they are separated by two more carbon atoms. Therefore, carbon atoms of a conjugated double bond are sp2 hybridized, whereas carbon atoms of a isolated double bond is one or more sp3 hybridized.

The each double bond in NPD1 as conjugated and isolated diene is shown below.

Interpretation Introduction

(b)

Interpretation: Neuroprotectin D1 is synthesized in the body from highly unsaturated essential fatty acids. NPD1 is a potent natural anti-inflammatory agent. The each double bond in NPD1 is to be labeled as E or Z.

Concept introduction: The prefix E and Z depends upon the location of the higher priority groups. When two higher priority groups are present on the opposite side then it is an E isomer, whereas when two higher priority groups are present on the same side then it is Z isomer.
