D
Triglycerides
Verified step by step guidance1
Understand the role of lipids in the body: Lipids serve various functions, including energy storage, structural components of cell membranes, and acting as chemical messengers.
Identify the lipid types listed in the problem: Steroids, phospholipids, waxes, and triglycerides. Each has distinct functions in the body.
Recall the function of steroids: Steroids are a class of lipids that include hormones like estrogen and testosterone. These hormones act as chemical messengers, regulating physiological processes such as growth, metabolism, and reproduction.
Compare the functions of the other lipids: Phospholipids primarily form cell membranes, waxes provide protective coatings, and triglycerides are used for energy storage. None of these act as chemical messengers.
Conclude that steroids are the correct answer because they are the lipid type primarily responsible for acting as chemical messengers in the body.
