Another very common type of molecule from which we can obtain energy are fats or is fat. Now, in fact, the majority of the energy that is stored in the human body is stored in fat, in special type of fat molecules known as triglycerides. So triglycerides are basically three fatty acids attached to a single glycerol backbone. 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.
