                                A fundamental biochemical fact is that exactly three fatty acids are required to form triacylglycerol, which is the body's main form of long-term energy storage. This crucial molecule, also known as a triglyceride, is formed through a dehydration synthesis reaction involving a single glycerol backbone.
