Feb 13, 2015· Brown fat . Whereas WAT is mainly used for energy storage, BAT contains more mitochondria (energy producing cell components) and has the capacity to generate heat by burning triglycerides. 31 Hybernating animals are known to use BAT to keep the adequate body temperature while in resting state. In humans, this specific type of tissue has

Why are fats used as storage molecules?

Fats are used as storage molecules because they give more ATP per molecule, they take less space to store and are less heavy than glucose. Fats are very misunderstood biomolecules. They are demonized for being unhealthy, and there was once a targeted strategy telling everyone to eat less fat. However, fat is essential to the body.

Fats as Energy Storage Molecules

Triglycerides are a form of long-term energy storage molecules. They are made of glycerol and three fatty acids. To obtain energy from fat, triglycerides must first be broken down by hydrolysis into their two principal components, fatty acids and glycerol. This process, called lipolysis, takes place in the cytoplasm.
