So a triglyceride is composed of three fatty acids and one glycerol. And in the same analogous way that we store our glucose in the form of glycologen, we store our fatty acids in the form of our triglyceride. So fats ingested into the body are stored in a specialized type of tissue known as adipose tissue and it is stored in the form of triglycerides. Now the question is, how exactly do we actually harvest the energy that is stored in triglycerides? In fact, how can we use that energy and transform that energy to form our ATP molecules that are used by our body? Now, basically, triglycerides have to undergo three important stages before we can actually obtain those ATP molecules.
