Developments in Ceramide Identification, Synthesis, Function and Nomenclature
By: Mike Farwick, Peter Lersch and Betty Santonnat…
Advances have been made in recent years to better understand ceramides, as the authors describe here. However, since not all ceramides have the same structure, the nomenclature in the literature and on product labels needs clarification. The Personal Care Products Council recently agreed upon new nomenclature based on four molecular structures, which the authors also discuss.
