Triglycerides and VLDL
Triglyceride is another form in which fat is transported through the blood to the body tissues. Most of the body's stored fat is in the form of triglycerides. Another lipoprotein—very low-density lipoprotein, or VLDL—has the job of carrying triglycerides in the blood.
It is not clear whether high levels of triglycerides alone increase an individual's risk of heart disease. However, they may be an important clue that someone is at risk of heart disease for other reasons.
