描述
Precorrin-2 belongs to tetrapyrroles and derivatives class of compounds. Those are polycyclic aromatic compounds containing four pyrrole rings joined by one-carbon units linking position 2 of one pyrrole ring to position 5 of the next. Precorrin-2 is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Precorrin-2 can be found in a number of food items such as plains prickly pear, rowanberry, fruits, and pigeon pea, which makes precorrin-2 a potential biomarker for the consumption of these food products.
