Chapter 2: Problem 9

Which of these lipids have regulatory roles in the body? a. steroids b. prostaglandins c. triglycerides d. both \(a\) and \(b\) e. both \(b\) and \(c\)

Short Answer

Expert verified
Steroids and prostaglandins have regulatory roles in the body, whereas triglycerides function primarily as a form of energy storage. Therefore, the correct answer is option (d) both \(a\) and \(b\).

Step by step solution

01

Investigate Steroids

Steroids are lipids that are made up of four interconnected carbon rings. They have hormone-like properties and play regulatory roles, such as controlling inflammation and regulating electrolytes. Some examples of steroids are cortisol and aldosterone.
02

Investigate Prostaglandins

Prostaglandins are a type of lipid compound derived from fatty acids. These lipids act as hormone-like signaling molecules and are involved in various physiological processes like inflammation, blood flow, and pain perception. Thus, prostaglandins also have regulatory roles in the body.
03

Investigate Triglycerides

Triglycerides are the main component of body fat and are the most common form of lipids in the body. They function primarily as a form of energy storage and are not known to have significant regulatory roles in the body.
04

Identify the Correct Option

Based on the information gathered, we can conclude the following: - Steroids have regulatory roles in the body. - Prostaglandins have regulatory roles in the body. - Triglycerides do not have regulatory roles in the body. Therefore, the correct answer is option (d) both \(a\) and \(b\).
