Questions: on 15 of 20 Which of the following INCORRECTLY matches the lipid with one of its primary functions in the body? cholesterol-used to synthesize steroid hormones triglycerides-a major component of cell membranes phospholipids-form the outer layer or "shell" of lipoproteins essential fatty acids—provide the required "parent" compounds needed to synthesize eicosanoids

The answer is the second one: triglycerides—a major component of cell membranes.

Explanation for each option:

1. Cholesterol-used to synthesize steroid hormones: This is correct. Cholesterol is a precursor for the synthesis of steroid hormones, such as cortisol, estrogen, and testosterone.

2. Triglycerides-a major component of cell membranes: This is incorrect. Triglycerides are primarily used for energy storage in adipose tissue and are not a major component of cell membranes. The major components of cell membranes are phospholipids.

3. Phospholipids-form the outer layer or "shell" of lipoproteins: This is correct. Phospholipids are a key component of the outer layer of lipoproteins, which transport lipids through the bloodstream.

4. Essential fatty acids—provide the required "parent" compounds needed to synthesize eicosanoids: This is correct. Essential fatty acids, such as omega-3 and omega-6 fatty acids, are precursors for the synthesis of eicosanoids, which are signaling molecules that play various roles in inflammation and other physiological processes.

Summary: The incorrect match is the second one: triglycerides—a major component of cell membranes. Triglycerides are primarily used for energy storage, not as a major component of cell membranes.
