Question

Arachidonic acid (5z,8z,11z,14z-eicosatetraenoic acid) is an eicosanoid, a fatty acid containing 20 carbon atoms. it is the precursor of the prostaglandins and leukotrienes, important signaling molecules. draw the line-bond structure of arachidonic acid. clearly show stereochemistry where appropriate.

Answer 1

Below is the structure of Arachidonic acid.

Arachidonic acid contains a chain of 20 carbon atoms. And there are four double bonds in this chain all having cis- Configurations at position 5, 8, 11 and 14 respectively.
