A method of detecting carboxyalkylpyrrole ethanolamine phospholipids (CAP-EPs) or pentylpyrrole ethanolamine phospholipids (CAP-EPs) in a bodily sample from a subject includes obtaining a bodily sample from a subject suspected of including carboxyalkylpyrrole ethanolamine phospholipids (CAP-EPs) or pentylpyrrole ethanolamine phospholipids (PP-EPs) extracting carboxyalkylpyrrole ethanolamine phospholipids or pentylpyrrole ethanolamine phospholipids from the bodily sample; hydrolyzing carboxyalkylpyrrole or pentylpyrrole ethanolamine phospholipids from the extracted with a phospholipase D to form carboxyalkylpyrrole ethanolamine (CAP-ETN) and pentylpyrrole ethanolamine (PP-ETN) derivatives; and determining the amount of carboxyalkylpyrrole ethanolamine (CAP-ETN) and pentylpyrrole ethanolamine (PP-ETN) by mass spectrometry.
