Description
1-Palmitoyl-2-hydroxy-
sn-glycero-3-PC is the ubiquitous lipid species generated following phospholipase A
2 (PLA
2) 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.
Chemical Properties
White Solid
Uses
16:0 Lyso PC has been used to reveal the central role of the adipocyte inflammasome in homocysteine-induced insulin resistance. It has also been used for lipid extraction and mass spectrometry analysis.
Uses
A lipid biomarker for stable and unstable heart disease.
Definition
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.
Biochem/physiol Actions
1-Palmitoyl-sn-glycero-3-phosphocholine may be used as a substrate to identify, differentiate and characterize lysophosphocholine acyl transferases.
