triglyceride

(Science: biochemistry) storage fats of animal adipose tissue where they are largely glycerol esters of saturated fatty acids.

Also found in the bloodstream with normal blood levels between 10-150 milligrams per decilitre. Elevations of the triglyceride level (particularly in association with elevated cholesterol) have been correlated with the development of atherosclerosis, the underlying cause of heart disease and stroke.

In plants they tend to be esters of unsaturated fatty acids (vegetable oils). Present as a minor component of cell membrane. Important energy supply in heart muscle.
