Identification
Common Namepheophorbide a
ClassSmall Molecule
DescriptionPheophorbide a is practically insoluble (in water) and an extremely strong acidic compound (based on its pKa). Pheophorbide a can be found in a number of food items such as chinese mustard, common persimmon, malabar plum, and black chokeberry, which makes pheophorbide a a potential biomarker for the consumption of these food products.
