1,2-DIMYRISTOYL-SN-GLYCERO-3-PHOSPHOETHANOLAMINE Structural

What is 1,2-DIMYRISTOYL-SN-GLYCERO-3-PHOSPHOETHANOLAMINE?

Description

Phosphatidylethanolamines (PEs) are phospholipids found in biological membranes, serving both structural and functional roles. Different types of PEs are commonly used in the generation of micelles, liposomes, and other types of artificial membranes. 1,2-Dimyristoyl-sn-glycero-3-PE (DMPE) is a phospholipid containing the long-chain (14:0) myristic acid inserted at the sn-1 and sn-2 positions.

The Uses of 1,2-DIMYRISTOYL-SN-GLYCERO-3-PHOSPHOETHANOLAMINE

Tetradecanoic Acid (1R)-1-[[[(2-Aminoethoxy)hydroxyphosphinyl]oxy]methyl]-1,2-ethanediyl Ester is a phospholipid serving both structural and functional roles in biological membranes.

What are the applications of Application

1,2-Dimyristoyl-sn-glycero-3-phosphoethanolamine is a high purity phospholipid utilized for liposome production

Purification Methods

Recrystallise the kephalin from EtOH [Bevan & Malkin J Chem Soc 2667 1951]. The R-isomer has m 195-196o (sintering at 130-135o) after recrystallisation from CHCl3/MeOH, and [] D 26 +6.7o (c 8.5, CHCl3/AcOH 9:1). [Baer Can J Biochem Physiol 35 239 1957, Baer et al.
