Phosphatidylcholine is a phospholipid, a type of fat molecule, that is a crucial component of all cell membranes in living organisms. It is composed of choline, phosphate, and two fatty acids. In biological systems, phosphatidylcholine plays a vital role in maintaining cell structure and integrity. It also acts as a precursor for the synthesis of other important molecules, including acetylcholine, a neurotransmitter, and diacylglycerol, a signaling molecule.

In the liver, phosphatidylcholine is essential for the packaging and transport of fats, particularly triglycerides and cholesterol, in the form of very-low-density lipoproteins (VLDL). This process is critical for delivering energy to the body's tissues. Deficiencies or abnormalities in phosphatidylcholine metabolism can contribute to various health conditions, such as fatty liver disease.

Phosphatidylcholine is also found in various food sources, including egg yolks, soybeans, and meats. In some instances, it is used as a dietary supplement. It is believed to support liver function and potentially aid in fat metabolism. Research into the specific health benefits and therapeutic applications of phosphatidylcholine is ongoing.
