Fatty acid amides (FAAs) are amides formed from a fatty acid and an amine.
In nature, many FAAs have ethanolamine as the amine component.
[1] FAAs play a role in intracellular signalling.
The signalling is controlled in part by fatty acid amide hydrolases, which convert the amide to the parent fatty acid.
One example of signaling is induced by the binding of anandamide to the cannabinoid receptors.
