Uses of Triglycerides
Function of Triglycerides
Triglycerides play a crucial function in humans:
- Used as energy storage molecules. Triglycerides are primarily used as energy storage molecules. During metabolic processes, such as respiration, the fatty acid chains of triglycerides can be broken down, in order to release very large amounts of stored chemical energy.
- Triglycerides are adapted to energy storage.
-
-
- Long hydrocarbon chains. The presence of long hydrocarbon chains in the fatty acids allows for a lot of chemical energy to be stored in them.

- Insoluble. The hydrophobic fatty acid chains arrange themselves to ‘hide away’ from water (Figure 8). Therefore triglycerides don’t affect the osmotic potential of cells, and do not cause swelling due to influx of water.

- Triglycerides are the main food store in humans. Triglycerides are so efficient at storing energy that triglycerides are able to store nearly twice as much energy as carbohydrates. Because of this, our bodily readily consumes carbohydrates and simple sugars for rapid energy boosts, and stores most of our consumed food in the form of fat.
- Bacteria also use triglycerides to store energy. Prokaryotes do not use triglycerides as widely as eukaryotes; however, certain groups of bacteria have also been demonstrated to use triglycerides as a reserve compound to store energy.
Triglycerides are a type of fat molecule found in food and in the human body. They are the most common form of fat and play an important role in energy storage.
Triglycerides serve as a source of energy for the body. They are stored in adipose tissue and can be broken down to release energy when needed. Triglycerides also help to insulate the body and protect vital organs.
Triglycerides are formed when excess glucose and other nutrients are converted and stored in adipose tissue. They can also be obtained from dietary fats.
Triglycerides can be broken down into their component fatty acids and glycerol, which can then be used as a source of energy by the body. This process is known as lipolysis.
High levels of triglycerides in the blood have been linked to an increased risk of heart disease. This is because high levels of triglycerides can contribute to the buildup of plaque in the arteries, which can lead to heart attack or stroke.
Triglyceride levels can be affected by factors such as diet, physical activity, and genetics. Consuming a diet high in saturated and trans fats, as well as simple sugars, can increase triglyceride levels. Physical activity and maintaining a healthy weight can help to lower triglyceride levels.
Reducing triglyceride levels in the body can be achieved by making lifestyle changes such as following a healthy diet low in saturated and trans fats, exercising regularly, and maintaining a healthy weight. In some cases, medication may also be prescribed to lower triglyceride levels.
The American Heart Association recommends that triglyceride levels should be below 150 mg/dL for adults. Levels between 150-199 mg/dL are considered borderline high, and levels above 200 mg/dL are considered high.
