Possibly of all the common phospholipids, least is known about plasmalogens. Although
plasmalogens represent one in every five phospholipids in the human body, one would be
hardpressed to find an adequate description of their structure or biosynthesis in
Biochemistry or Cell Biology textbooks. This lack of knowledge is, in part, due to the fact that
plasmalogens are a subclass of phospholipid and, unlike other phospholipids, are not
defined by the polar head group. It is not possible to separate them from other phospholipids …
