  • It belongs to the group of glycosphingolipids.
  • They are characterized by the presence of sialic acids (acylated neuraminic acids).
  • The presence of various fatty acids and sphingosine base.
  • Compared to other glycosphingolipids, they have a different spectrum of fatty acids (stearic acid 90%).
  • They contain carbohydrate units (cause higher solubility in water).
