Simple Reactions of Chlorophyll
of cholorophyll-a with acid removes the magnesium ion replacing it
with two hydrogen atoms giving an olive-brown solid, phaeophytin-a.
Hydrolysis of this (reverse of esterification) splits off phytol and gives
phaeophorbide-a. Similar compounds are obtained if chlorophyll-b
Overall reaction scheme for the hydrolysis of chlorophyll.
Chlorophyll can also be reacted with a base which yields a series of phyllins, magnesium porphyrin compounds. Treatment of phyllins with acid gives porphyrins.
