triglycerides


Triglycerides are the chemical form in which most fat exists in food as well as in the body. They circulate in the blood plasma and, in association with cholesterol, form the plasma lipids. Triglycerides come from fats eaten in foods or made in the body from other energy sources like carbohydrates. Calories eaten that are not used immediately by tissues, are then converted to triglycerides and transported to fat cells to be stored and used by the body as an energy source between meals. Hormones regulate the release of triglycerides from fat tissue so they meet the body's needs for energy.
