                                Over half of the lipids in eukaryotic cell membranes are composed of phosphatidylcholine, the most abundant phospholipid. Phospholipids are a major class of lipids crucial for cell structure, fluidity, and communication, serving as the fundamental building blocks of biological membranes across all life forms.
