About the structure and biological function of PC
Structure. Phosphatidylcholines (lecithins, PtdCho, GPCho, or PC) are a type of glycerophosphocholines, a class of glycerophospholipids. Their structure consists of a glycerol backbone linked to two fatty acids and a phosphocholine molecule. The fatty acids can be of variable length, hydroxylated, and contain double bonds.
Phosphatidylcholines are mainly found in eukaryotes. On a subcellular level, they are enriched in cell membranes and in lipoprotein particles of blood plasma.
Function. Phosphatidylcholines serve as key building blocks for biological membranes, and they play an important role in plasma lipoproteins, the biochemical structures to transport lipids in blood plasma. Phosphatidylcholine is a precursor of acetylcholine, a neurotransmitter. Platelet-activating factor is a phosphatidylcholine. Phosphatidylcholines are elevated in cancers because of the increased demand for membrane constituents, and linked to liver conditions such as non-alcoholic fatty liver disease.
Breast Cancer & Lipid Metabolism
Breast cancer phospholipid metabolism is a powerful target for new therapies, especially against triple-negative breast cancer.
