DPA (docosapentaenoic acid) is an omega-3 fatty acid.
These are a family of fatty acids that are essential for our bodies.
DPA is a precursor to DHA.
Characteristics and sources of n-3 DPA
Structure and definition
Docosapentaenoic acid (n-3 DPA) is an omega-3 polyunsaturated fatty acid with 22 atoms (like DHA) and 5 double bonds (like EPA).
The n-3 designation is important for n-3 DPA because there is also an omega-6 version of DPA, called n-6 DPA, which differs from n-3 DPA in the location of the first double bond in the fatty acid.
Metabolic pathways
Thus, n-3 DPA is an intermediate metabolite between eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA):
- EPA metabolite
- Immediate precursor of DHA
Food sources of n-3 DPA
Herring and sardines (as well as all fish in the Clupeidae family) contain significant amounts of n-3 DPA (hence the name clupanodonic acid, synonymous with DPA).
It should be noted that the fat of seals, walruses and sea lions is also particularly rich in n-3 EPA.
Role of n-3 DPA in the body
Consumption of n-3 DPA contributes to the daily intake of omega-3 fatty acids.
n-3 DPA does not benefit from approved health claims in its own name, as it is primarily an intermediate, but its health properties obviously derive from its role as a precursor to DHA.
