- Any of various pigments distributed widely in living tissues
- Porphyrins are a group of organic compounds of which many occur in nature. One of the best known is heme, the pigment in red blood cells. Heme is a cofactor of the protein hemoglobin. ...
- Any of a class of heterocyclic compounds containing four pyrrole rings arranged in a square; they are important in biochemistry in a form with a metal atom in the central cavity (hemoglobin with iron, chlorophyll with magnesium, etc.)
- (Porphyrins) A chemical released by the skin bacteria Propionobacterium acnes, which causes acne.
- A porphin derivatives in which the pyrrole beta-carbons are variously substitued. Porphyrin can readily chelate vrious metals, the metalloporphyrins being components of several important biological pigments, e.g. chlorophylls, cytochromes, haem.
- A large molecule shaped somewhat like a four-leaf clover. Combined with an iron atom, it forms a heme molecule.
- A complex planar structure containing four substituted pyrroles covalently joined in a ring and frequently containing a central metal atom. For example, heme is a porphyrin with a central iron atom.
- The proper word for the red/reddish brown fluid produced from the rats mucous glands. Produced in excess it can stain the fur (particularly light coloured fur) and is a sign of stress and illness. Most commonly seen around the nose it can also flow from the eyes. ...
- Compounds of a structure that consists of four pyrrole rings joined by four =C- groups; esp: one (as chorophyll or hemoglobin) containing a central metal atom, and usually having biological activity.
