Docosapentaenoic acid designates any straight chain 22:5 fatty acid.


See essential fatty acid#nomenclature for nomenclature.

all-cis-4,7,10,13,16-docosapentaenoic acid (osbond acid)[edit]

The chemical structure of osbond acid showing physiological numbering (red) and chemical numbering (blue) conventions.

all-cis-4,7,10,13,16-docosapentaenoic acid is an ω-6 fatty acid with the trivial name osbond acid. It is formed by an elongation and desaturation of arachidonic acid 20:4 ω-6.

all-cis-7,10,13,16,19-docosapentaenoic acid (clupanodonic acid)[edit]

The chemical structure of clupanodonic acid showing physiological numbering (red) and chemical numbering (blue) conventions.

all-cis-7,10,13,16,19-docosapentaenoic acid is an ω-3 fatty acid with the trivial name clupanodonic acid, commonly called DPA. It is an intermediary between eicosapentaenoic acid (EPA, 20:5 ω-3) and docosahexaenoic acid (DHA, 22:6 ω-3). Seal oil is a rich source.[1]

Docosapentaenoic acid deficiency[edit]

In mammals, clupanodonic acid (ω-3 fatty acid) deficiency is accompanied by an increase of the osbond acid (ω-6 fatty acid) isomer; the Osbond/DHA ratio is thus a marker of dietary DHA sufficiency.[2] However, this usage has been questioned.[3]
