Definition:A dihydroxydocosahexaenoic acid that is (4Z,7Z,11E,13E,15Z,19Z)-docosahexaenoic acid in which the two hydroxy substituents are located at positions 10 and 17 (the 10R,17S-stereoisomer). Protectin D1 is one of the specialised proresolving mediators. When produced in neural tissues, it is called neuroprotectin D1
