While most commonly known as the building blocks of cell membranes, recent research has clarified the role of glycerophospholipids beyond simple structural support. Under certain conditions, these molecules are broken down and their components are channeled into energy-producing pathways, confirming that glycerophospholipids can be used for energy. This metabolic flexibility is crucial for cellular function, particularly in times of high metabolic stress.

Lipids, primarily stored as triglycerides, are the most energy-dense macromolecules, yielding more than twice the energy per unit mass compared to carbohydrates. To harness this vital energy, a series of complex metabolic pathways detailing the processes that may be involved in the breakdown of lipids are required.

The human body stores fat in adipose tissue as a crucial long-term energy reserve. When the body needs energy, the catabolic process of breaking down these complex lipid molecules is initiated. This series of biochemical reactions, known as lipid catabolism, yields several significant results that fuel cellular functions and maintain metabolic balance.
