Abstrakt: Spectrophotometric studies on the behaviour of coproferrihaem in aqueous solution showed that, in the pH range 6.66–8.04, a dimerization process occurs according to the equation 2 monomer The value of K, the pH-independent dimerization contant, was found to be 2.10 · 10−3, signifying that coproferrihaem shows the least tendency to dimerize of any ferrihaem so far investigated. Forward and reverse rate constants for the dimerization process have been determined by the temperature-jump method.
