General description

1-O-Acyl-Ceramide is an epidermal ceramide present in mouse and human epidermis. It comprises long chain fatty acids in 1-O-position and is synthesized in the endoplasmic reticulum-related sites.


1-O-Acyl-Ceramide is suitable for use as a lipid standard in
  • high performance thin layer chromatography (HPTLC)
  • in mass and nuclear magnetic resonance spectroscopy for the quantification of lipids isolated from vernix caseosa skin cream
  • in liquid chromatography-tandem mass spectrometry for the quantification of 1-O-Acyl ceramides from liver samples

Biochem/physiol Actions

1-O-Acyl-Ceramide functions in maintaining water barrier homeostasis. Deficiency of the glucosylceramide synthase enzyme leads to the accumulation of O-acylceramides. Treatment of human monoclonal antibody, REMD 2.59 leads to the accumulation of 1-O-acyl-ceramides in soleus muscle and depletion in liver.

Except for epidermis and liver, little is known about endogenous expression of 1-O-acylceramides (1-OACs) in mammalian tissue. Therefore, we screened several organs (brain, lung, liver, spleen, lymph nodes, heart, kidney, thymus, small intestine, and colon) from mice for the presence
