  <name>Palmitoleoyl ethanolamide</name>
  <description>Palmitoylethanolamide (PEA) is an endogenous fatty acid amide. PEA has been shown to have anti-inflammatory[2] and anti-nociceptive properties.

PEA is metabolized by fatty acid amide hydrolase (FAAH) and N-acylethanolamine-hydrolyzing acid amidase (NAAA), the latter of which has more specificity toward PEA over other fatty acid amides. [HMDB]</description>
