Concept Introduction:
Steroids are types of lipids which consist of three 6-membered rings and one 5-membered ring. These all rings together are known as steroid nucleus. Other polar and non-polar groups are bonded with these rings and are responsible for different physical and chemical properties of steroids.
Many steroids act as hormones in living organisms. A hormone can be defined as the
(b)
Interpretation:
The double bonds in the skeleton formula of LTC4 should be labeled as cis or trans.

Many steroids act as hormones in living organisms. A hormone can be defined as the biomolecule that is secreted in one part of the living organism but elicits a response in another part of the body. They transfer from one part to another part in the body through blood.
