Distearoylphosphatidylcholine is a phosphatidylcholine, a kind of phospholipid. It is a natural constituent of cell membranes, eg. soybean phosphatidylcholines are mostly different 18-carbon phosphatidylcholines (including minority of saturated DSPC), and their hydrogenation results in 85% DSPC.[1] It can be used to prepare lipid nanoparticles which are used in mRNA vaccines,[2][3] In particular, it forms part of the drug delivery system for the Moderna and Pfizer COVID-19 vaccines.[4][5]
