Answer to Question 2

Both are forms of the chlorophyll pigment. Pheophytin is formed by the reaction with acid and the loss of the magnesium from the center of the molecule. It is an olive green color. Chlorophyllin is formed with the reaction with alkali and the loss of the phytyl and methyl group. This is a non-food green.
