Question

Prostaglandins and steroids share which of the following characteristics?

a. Both are found in the cell membrane.
b. Both have a ring structure in their molecule.
c. Both have a saturated fat in their structure.
d. None of the above are shared characteristics.

Answer 1

Prostaglandins and steroids both have a ring structure in their molecule. They are important components of cell membranes and have various physiological functions.

Step-by-step explanation:

Prostaglandins and steroids share the characteristic that both have a ring structure in their molecule. Prostaglandins are lipids containing 20 carbon atoms and are derived from arachidonic acid, while steroids have a core of seventeen carbon atoms arranged in four rings. Both prostaglandins and steroids are important components of cell membranes and have various physiological functions in the body.
