The organs that use fatty acids are the liver, skeletal muscle and adipose tissue.
Most tissues in the body are involved in metabolism of fatty acids but the above tissues and organs are more important than others.
Each of these organs and tissues has a store of triacylglycerol which can be hydrolysed or mobilized in a regulated way to release the fatty acids.
The liver is the central organ for fatty acid metabolism.
Fatty acids accrue in liver by way of hepatocellular uptake from the plasma and by de novo biosynthesis.
Fatty acids are then eliminated by oxidation within the cell or by secretion into the plasma within triglyceride-rich very low density lipoproteins.
A variety of fatty acids exists in the diet of humans, in the bloodstream of humans, and in cells and tissues of humans.
Fatty acids are energy sources and membrane constituents.
They have biological activities that act to influence cell and tissue metabolism, function, and responsiveness to hormonal and other signals.
Fatty acids have many important functions in the body, including energy storage.
If your glucose (a type of sugar) isn't available for energy, the body uses fatty acids to fuel the cells instead.
After the fat has been digested, fatty acids are passed through the lymph system and then throughout the body via your bloodstream to be used or stored for energy, cell repair, and growth.
Your lymph system also absorbs fatty acids to help fight infection.
