Structure of Triglycerides

Triglycerides are composed of a glycerol molecule and three fatty acid molecules. The fatty acids can be saturated (no double bonds between carbon atoms) or unsaturated (one or more double bonds between carbon atoms). The type of fatty acids in the triglyceride affects its physical properties, such as its melting point.

Functions of Triglycerides

Triglycerides serve as a source of energy for the body. They are also important for storing energy for later use. Additionally, they provide insulation and help protect organs in the body.

Metabolism of Triglycerides

When you consume more calories than your body needs, the excess calories are converted into triglycerides and stored in fat cells. Later, when your body needs energy between meals, hormones release the triglycerides from fat cells and they are broken down into fatty acids and glycerol. These components are then used for energy production in various tissues of the body.

Factors Affecting Triglyceride Levels

Several factors can influence triglyceride levels in the body, including diet, physical activity, genetics, and certain medical conditions such as diabetes and hypothyroidism.
