1-Palmitoyl-2-hydroxy-sn-glycero-3-PC is the ubiquitous lipid species generated following phospholipase A₂ (PLA₂) hydrolysis of phosphatidylcholine. It increases the production of reactive oxygen species (ROS) and decreases superoxide dismutase (SOD) and endothelial nitric oxide synthase (eNOS) protein levels and phosphorylation of ERK1/2 in human umbilical vein endothelial cells (HUVECs) when used at a concentration of 125 μM. 1-Palmitoyl-2-hydroxy-sn-glycero-3-PC potentiates the secretion of IL-6, IL-1β, IL-12, and TNF-α in LPS-stimulated M1 macrophages, but has no effect on CD163, CD206, CD36, or IL-10 in LPS-stimulated M2 macrophages when used at concentrations of 0.3 and 1.0 μM. It increases TGF-β1 production and enhances Foxp3 protein levels in T_reg cells in isolated human peripheral blood when used at a concentration of 10 μM. 1-Palmitoyl-2-hydroxy-sn-glycero-3-PC enhances neutrophil function, bacterial clearance, and survival in mouse models of sepsis when administered at a dose of 10 mg/kg.

ChEBI: 1-hexadecanoyl-sn-glycero-3-phosphocholine is a lysophosphatidylcholine 16:0 in which a hexadecanoyl (palmitoyl) group is attached to the glycero moiety at position 1. It has a role as a mouse metabolite. It is a lysophosphatidylcholine 16:0 and a 1-O-acyl-sn-glycero-3-phosphocholine.

1-Palmitoyl-sn-glycero-3-phosphocholine may be used as a substrate to identify, differentiate and characterize lysophosphocholine acyl transferases.

This lysolecithin (FW = 495.64 g/mol; CAS 17364-16-8), also known as 1- palmitoylglycerophosphocholine or lysophosphatidylcholine (palmitate- containing), is the hydrolysis reaction product formed by phospholipase A2 and is a substrate for 1-acylglycerophosphocholine O-acyltransferase, lysophospholipase, and lysolecithin acylmutase. Note: Because palmitoylglycero-phosphocholine readily forms micelles, one must take care to discriminate whether the monomeric and/or micelle form (s) is (are) inhibitory, when palmitoylglycero-phosphoryl choline is present above the critical micelle concentration (cmc).
