In olive oil,when oleic acid in triglycerid place in mid position,its benefits on health (Cardiovascular Disease,etc) is more than when oleic acid place in the two other sides?
The fats (triglycerides) in food are made up of a glycerol with three fatty acids attached. There are many different types of fatty acids such as oleic acid, linoleic acid, etc. They are like three flags flying on the glycerol flagpole. You seem to be alluding to the fact that different flags can fly in different order from up to down on the pole. But this should make no difference because in your intestine lipase enzymes and bile acids break down the glycerol and fatty acids, destroying the order. The glycerol and fatty acids pass into the intestinal lining cells separately. These cells then reform the triglyceride stringing the fatty acid "flags" on the glycerol "flagpole" in on order to their liking.
