Question:

What are the building blocks of lipids?

Expert Verified Solution:

Lipids, which are essential macromolecules in living organisms, are primarily built from two types of molecules: glycerol and fatty acids. Glycerol is a three-carbon alcohol that serves as the backbone, while fatty acids are long hydrocarbon chains that attach to glycerol. These components form various types of lipids, such as triglycerides and phospholipids. Triglycerides, which are a common form of fat, consist of one glycerol molecule bonded to three fatty acid chains. Phospholipids, which are key components of cell membranes, consist of a glycerol molecule, two fatty acids, and a phosphate group. These structures allow lipids to perform crucial functions in energy storage, cell membrane structure, and signaling within the body. Understanding these building blocks is vital in comprehending how lipids contribute to biological processes.
