Biological Activity: 1-Stearoyl-2-linoleoyl-sn-glycero-3-phosphocholine (SLPC; 18:0-18:2 PC) is an endogenous phospholipid marker molecule in the glycerophospholipid metabolic pathway. 1-Stearoyl-2-linoleoyl-sn-glycero-3-phosphocholine is a core component of the phospholipid bilayer of biological membranes and a key responsive lipid for radiation injury and cardiometabolic diseases. 1-Stearoyl-2-linoleoyl-sn-glycero-3-phosphocholine constitutes the phospholipid bilayers of cell membranes and high-density lipoprotein (HDL), and regulates the core activity of lipoprotein functional homeostasis. The content of 1-Stearoyl-2-linoleoyl-sn-glycero-3-phosphocholine in mouse serum shows a significant dose-dependent decrease with increasing ionizing radiation dose, and its level in human HDL also decreases significantly in metabolic syndrome. 1-Stearoyl-2-linoleoyl-sn-glycero-3-phosphocholine can serve as a biological dosimeter marker for ionizing radiation injury, and is used for rapid and accurate assessment of radiation absorbed dose in exposed individuals. 1-Stearoyl-2-linoleoyl-sn-glycero-3-phosphocholine can also act as a lipidomics research target for cardiometabolic diseases such as lipid metabolic syndrome and early-onset coronary heart disease^[1][2].
