Chlorophyllin is a derivative of cholorophyll, the green pigment present in the plants. Plants primarily contain two types of chlorophylls namely cholorophyll A and cholorophyll B. Most green plants contain chlorophyll A where as all greaan vegetables contain both cholorophyll A as well as B.
The basic structure of chlorophyll is a porphyrin ring with magnesium as the central stom. The structure is similar to that of haemoglobin just that it has iron at its centre. It has a long hydrocarbon tail attached to it and that is what makes chlorophyll fat-soluble
