What is the liver's role in the metabolism of fatty acids?

The liver plays a crucial role in the metabolism of fatty acids, primarily by synthesizing them for energy. This process is known as lipogenesis, where excess carbohydrates and proteins are converted into fatty acids, which can then be stored as triglycerides or oxidized to produce energy. The liver is capable of managing the balance of fatty acid levels in the body, contributing to energy homeostasis.

While the liver does have functions related to glucose and storage, the synthesis of fatty acids is a specific metabolic pathway that demonstrates the liver’s role in energy metabolism. It is important to recognize that fatty acids can be broken down through a process called β-oxidation; however, the primary focus here is on their synthesis and contribution to energy availability. The other functions related to glucose conversion and urea production do not accurately reflect the primary metabolic role of fatty acids in the liver.
