Chemical compound

Stearoylethanolamide (SEA) is an endocannabinoid neurotransmitter.^[1]

Stearoylethanolamide (C₂₀H₄₁NO₂; 18:0), also called N-(octadecanoyl)ethanolamine, is an N-acylethanolamine and the ethanolamide of octadecanoic acid (C₁₈H₃₆O₂; 18:0) and ethanolamine (MEA: C₂H₇NO), and functionally related to an octadecanoic acid.^[2]

Levels of SEA correlate with changes in pain intensity, indicating this SEA change, reflect the pain reduction effects of IPRP.^[3]
