  <name>PGD2 ethanolamide</name>
  <description>PGD2 ethanolamide is a N-acylethanolamine. N-acylethanolamines (NAEs) constitute a class of lipid compounds naturally present in both animal and plant membranes as constituents of the membrane-bound phospholipid, N-acylphosphatidylethanolamine (NAPE). NAPE is composed of a third fatty acid moiety linked to the amino head group of the commonly occurring membrane phospholipid, phosphatidylethanolamine. NAEs are released from NAPE by phospholipase D-type hydrolases in response to a variety of stimuli. Transient NAE release and accumulation has been attributed a variety of biological activities, including neurotransmission, membrane protection, and immunomodulation in animals. N-oleoylethanolamine is an inhibitor of the sphingolipid signaling pathway, via specific ceramidase inhibition (ceramidase converts ceramide to sphingosine). N-oleoylethanolamine blocks the effects of TNF-  and arachidonic acid on intracellular Ca concentration. (PMID: 12692337, 12056855, 12560208, 11997249) [HMDB]</description>
