Definition : Porphyrins which are combined with a metal ion. The metal is bound equally to all
four nitrogen atoms of the pyrrole rings. They possess characteristic absorption spectra
which can be utilized for identification or quantitative estimation of porphyrins
and porphyrin-bound compounds. [MeSH];
