Concerned about fat Dear Concerned, Fat can be carried in the blood in the form of triglycerides, which are made up of three fatty acids attached to a glycerol backbone. As you probably know, fats are not soluble in water. The triglycerides in these VLDL packages are measured to give a serum triglyceride value. In order to understand what to do about elevated serum triglycerides, it is important to understand where triglycerides come from, and the conditions under which they are made.
Serum triglycerides come from two sources.
One is the food you eat. After you eat a fatty meal, the intestines package some of these fats in VLDL's for transport to your liver. You should consult with your physician to find out which of these conditions may be responsible for your elevated serum triglycerides. The most common reason for having elevated serum triglycerides concern blood sugar availability and handling. If you have stored fuel in the form of fat, your fat cells respond to this starvation by sending out free fatty acids into your blood stream.
