Triglycerides are a type of fat (lipid) found in the blood, formed from the combination of glycerol and three fatty acids. They serve as a primary source of energy for the body and are stored in adipose (fat) tissue. Elevated levels of triglycerides can be associated with an increased risk of cardiovascular disease and are often influenced by diet, physical activity, and overall health. Monitoring triglyceride levels is important for assessing metabolic health.
