    Sep 03 2019 · Pheophytin is a grey pigment related to Chlorophyll with the difference of that its Porphyrin ring does not have Magnesium ion in the center but two different protons instead. However like Chlorophyll it has Porphyrin A with a methyl group and Porphyrin B with a aldehyde group making B more polar than A and thus A not really visible as well.
