1,2-Dipalmitoyl-sn-glycero-3-phosphoethanolamine (DPPE), a phospholipid member of glycerophosphonoethanolamine family, is a major component in biological membranes. Studies focused on interactions between DPPE and cholesterol show that cholesterol induces condensation of DPPE monolayers in the presence of Ca2+ ions. Membranes containing a higher concentration of this compound contain more ordered lipid tails which results in a thicker membrane. Increasing DPPE concentrations has also been noted to cause competitive hydrogen bonding between amine groups and phosphate/carbonyl groups or water.1,2-二棕榈酰-sn-甘油-3-磷酸乙醇胺可用于构建膜结构 。 1,2-Dipalmitoyl-sn-glycero-3-phosphoethanolamine (DPPE), a phospholipid member of glycerophosphonoethanolamine family, is a major component in biological membranes.
