Translations:Docosahexaenoic acid/10/en

1. a desaturation at the sixth carbon of alpha-linolenic acid by a delta 6 desaturase to produce stearidonic acid (SDA, 18:4 ω-3),
2. elongation of the stearidonic acid by a delta 6 elongase to produce eicosatetraenoic acid (ETA, 20:4 ω-3),
3. desaturation at the fifth carbon of eicosatetraenoic acid by a delta 5 desaturase to produce eicosapentaenoic acid (EPA, 20:5 ω-3),
4. elongation of eicosapentaenoic acid by a delta 5 elongase to produce docosapentaenoic acid (DPA, 22:5 ω-3), and
5. desaturation at the fourth carbon of docosapentaenoic acid by a delta 4 desaturase to produce DHA.
