dspe

1,2-Distearoyl-sn-glycero-3-phosphorylethanolamine (1,2-DSPE) is a phosphatidylethanolamine (PE or GPEtn). The stearic acid moieties are derived from animal fats, cocoa butter, and sesame oil. Phospholipids are ubiquitous in nature and are key components of the lipid bilayer of cells, as well as being involved in metabolism and signaling.

DGTS, a structural isomer of DGTA and one of the most prevalent betaine lipids in microalgae, particularly in Chlorophyceae [1], functions as a helper lipid similar in structure to DSPE or DOPE.
