Structure of Triglycerides

Triglycerides are composed of a glycerol molecule and three fatty acid molecules. The fatty acids can be saturated or unsaturated, and their composition determines the physical properties of the triglyceride.

Functions of Triglycerides

1. **Energy Storage**: Triglycerides serve as a concentrated source of energy in the body. When the body needs energy, triglycerides are broken down into fatty acids and glycerol, which can be used to produce ATP, the body's primary energy currency.2. **Insulation and Protection**: Triglycerides are stored in adipose tissue, where they provide insulation and protection for organs in the body.3. **Cellular Structure**: Triglycerides are important components of cell membranes and play a role in maintaining the integrity and fluidity of cell membranes.

Triglycerides in Foods

Triglycerides are found in various foods, including oils, butter, meats, dairy products, and certain plant-based foods. Consuming excessive amounts of triglycerides, especially from sources high in saturated fats, can contribute to health issues such as obesity and cardiovascular disease.
