ΚΠ

1926 Proc. Royal Soc. B. 100 419 When iron combines with hæmatoporphyrin to give a hæmatin, the spectrum resembles that of a typical metallo-porphyrin only when the pigment is in the form of hæmochromogen.

1933 S. W. Cole Pract. Physiol. Chem. (ed. 9) x. 254 The porphyrins combine with various metals, other than iron, to form a series of metalloporphyrin compounds.

1960 Science 19 Feb. 480/2 Similar metalloporphyrins are the active components of chlorocruorins, chlorophylls, hemoglobins, cytochromes, peroxidases, and catalases.

1992 C. A. Smith & E. J. Wood Biosynthesis ix. 206 The pathway leading to the synthesis of two metalloporphyrins, haem and chlorophyll, are common up to the intermediate, protoporphyrin.
