Triglycerides serve as the primary energy storage form of fat in the body. They are composed of three fatty acid molecules attached to a glycerol backbone. Triglycerides store excess energy derived from food, which the body can later use for fuel during periods of energy deficit, such as between meals or during physical activity. Beyond energy storage, they also provide insulation and protection for vital organs and play a role in hormone regulation. It's essential to maintain healthy triglyceride levels, as elevated levels may contribute to cardiovascular diseases and other health issues.
