Metabolite Identification
Common NamePyrophaeophorbide a
DescriptionPyrophaeophorbide a belongs to the class of organic compounds known as chlorins. These are large heterocyclic aromatic ring systems consisting, at the core, of three pyrroles and one pyrroline coupled through four methine linkages. Pyrophaeophorbide a is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review very few articles have been published on Pyrophaeophorbide a.
