Glycerophospholipids vs. Sphingolipids: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on December 10, 2023
Glycerophospholipids contain glycerol, fatty acids, phosphate, and an alcohol; sphingolipids are based on sphingosine, with fatty acids and varying head groups.

Key Differences

Glycerophospholipids are a major component of cell membranes, consisting of glycerol backbone linked to two fatty acids and a phosphate group. Sphingolipids, on the other hand, have a sphingosine backbone and are involved in signal transmission and cell recognition.
