L-α-Phosphatidyl-D-myo-inositol 4-monophosphate, dipalmitoyl ammonium salt

L-α-Phosphatidyl-D-myo-inositol 4-monophosphate, dipalmitoyl ammonium salt is a synthetic phospholipid that plays an important role in non-medical research, particularly in the study of lipid membranes and their biophysical properties. This molecule consists of a glycerol backbone esterified with two palmitic acid chains, combined with a myo-inositol ring phosphorylated at the 4th position, and the entire structure is neutralized by an ammonium salt. The dipalmitoyl component provides hydrophobic stability to the molecule, making it an ideal candidate for forming stable bilayers in model membrane systems. The phosphorylated inositol headgroup introduces a specific charge and polar interaction dynamics, which are critical in the study of membrane signaling pathways and lipid interactions. This compound is extensively used in the exploration of membrane dynamics, particularly how phosphoinositide-specific phosphorylation can influence membrane curvature, charge distribution, and interaction with proteins. In research settings, such as in materials science and nanotechnology, this lipid is instrumental in designing mimetic membranes that replicate certain cellular behaviors in a controlled environment, thereby providing insights into the fundamental aspects of membrane mechanics and interactions without the influence of living biological systems.
