Three groups of lipids found naturally in the body and food?

• A. Triglycerides, Phospholipids, Sterols
• B. Triglycerides, Glycolipids, Sterols
• C. Phospholipids, Glycolipids, Sphingolipids
• D. Glycolipids, Sterols, Cholesterol

Answer: (A)

Three broad lipid groups commonly discussed in nutrition are triglycerides, phospholipids, and sterols. Triglycerides are the main form of dietary and stored fat, made of a glycerol backbone with three fatty acids attached. They supply most of the energy in our diet and are stored in fat tissue for later use. Phospholipids have a glycerol backbone with two fatty acids and a phosphate-containing head group. They are essential components of cell membranes, forming the lipid bilayer that protects and organizes cells, and they also help with signaling and fat digestion. Sterols have a ring structure, with cholesterol being the most familiar in the body. They contribute to membrane structure and serve as precursors to bile acids and steroid hormones; plant sterols can affect lipid absorption. Other lipid types like glycolipids or sphingolipids exist, but they’re not the three main groups highlighted in basic nutrition. So the trio that fits the standard categorization is triglycerides, phospholipids, and sterols.
