Biochemistry Western Governors University A: Fats are made up fatty acids and a glycerol. They are stored in cells known as adipocytes throughout the body. When the body needs energy the stored fats are broken down through the process of metabolism and beta oxidation (Livestrong.com‚ n.d.). For example‚ triacylglyceride or triglyceride are broken down into their separate parts‚ fatty acid chains and a glycerol. The body will always metabolize the glycerol first because it is easier

Lipids‚ which are also known as fats play a very important part in our bodies‚ it provides energy to producing hormones. As humans we wouldn’t be able to digest and absorb food without lipids. Eating more fat than we need can lead to weight gain but with proper amounts of lipids they are a healthy part of our diet.
