Description

In biochemistry, eicosanoids are signaling molecules made by oxidation of twenty-carbon essential fatty acids, (EFAs). They exert complex control over many bodily systems, mainly in inflammation or immunity, and as messengers in the central nervous system. Source: Wikipedia.

This pathway has been updated with information from Lipidmaps>Eicosanoids [1]. Metabolites and proteins from this pathway are orange coloured and have an rounded rectangle shape (where an oval shape indicates that the node only occures in the LipidMaps pathway). Reactions occurring in the lipidmaps pathways are coloured orange (where a dashed line indicates that the reaction only occures in the LipidMaps pathway).
