Abstract

Chlorophyll (Chi) a and its C-10 epimer, Chi a′, are compared for pheophytinization (demetallation) kinetics in aqueous acetone containing HC1. For each pigment the pheophytinization rate is of second order with respect to proton, and under identical conditions Chi a′ is pheophytinized by roughly 50% faster than Chi a, due probably to weaker Mg-N bonds in Chi a′.
