homeostasis. (Discuss) Proposed since August 2010.| Blood lipids
(or blood fats) are lipids in the blood, either free or bound to
other molecules. They are mostly transported in a protein
capsule, and the density of the lipids and type of protein
determines the fate of the particle and its influence on
metabolism. The concentration of blood lipids depends on intake
and excretion from the intestine, and uptake and secretion from
cells. Blood lipids are mainly fatty acids and cholesterol.
Hyperlipidemia is the presence of elevated or abnormal levels of
lipids and/or lipoproteins in the blood, and is a major risk
factor for cardiovascular disease. Fatty acids  Intestine intake
Short- and medium chain fatty acids are absorbed directly into
the blood via intestine capillaries and travel through the
portal vein. Long-chain fatty acids, on the other hand, are too
large to be directly released into the tiny intestine
capillaries. Instead they are coated
