Products >>Protoporphyrin
A metal-free porphyrin, C32H32N4(COOH)2, that combines with ferrous iron to form the heme group in hemoglobin and myoglobin, and with ferric iron to form the hemin group in catalase and some cytochromes.
It is suggested that PPN can be extracted from anti-coagulated porcine blood. PPN can inhibit HBV-DNA expression and duplication ih vitro, and has no cytotoxicity to liver cells.
