So number one is their highly reduced molecules and number two is their anhydrous. Now, what do we mean by highly reduced? Well, essentially, we have removed lots of electrons from the triglycerides. We have removed lots of electrons from the fatty acids. And that's important because we can actually break down the triglycerides via oxidation many, many times to produce a large number of molecules that we can then use to help generate those ATP energy molecules. The second reason is the fact that it's anhydrous.
