描述
Chlorophyllide b is a member of the class of compounds known as metallotetrapyrroles. Metallotetrapyrroles are polycyclic compounds containing a tetrapyrrole skeleton combined with a metal atom. Chlorophyllide b is practically insoluble (in water) and an extremely strong acidic compound (based on its pKa). Chlorophyllide b can be found in a number of food items such as cardoon, peach (variety), lime, and loquat, which makes chlorophyllide b a potential biomarker for the consumption of these food products.
