Cyclic organic molecule containing an iron atom that carries oxygen in hemoglobin and carries an electron in cytochromes.
An iron-porphyrin compound that occurs as a prosthetic group in hemoproteins.
a constituent of the hemoglobin molecule that consists of a globin and four home units. Each heme unit contains an atom of iron.
Heme groups are the part of hemoglobin that actually bind the oxygen molecules. Each heme group contains an iron atom that is held in the center of the heme. The iron is responsible for the oxygen-binding activities of hemoglobin.
a complex red organic pigment containing iron and other atoms to which oxygen binds
a very stable structure of a ring like organic compound called porphyrin bound to an iron atom (p
A porphyrin ring containing a central iron atom that can reversibly bind oxygen molecules; a component of the hemoglobin molecule.
A deep red pigment (C34H32N4O4Fe) which contains reduced (ferrous) iron.
The deep red iron-containing hemoglobin found in foods of animal origin.
A compound made mostly of iron.
A heme or haem is a prosthetic group that consists of an iron atom contained in the center of a large heterocyclic organic ring called a porphyrin. Not all porphyrins contain iron, but a substantial fraction of porphyrin-containing metalloproteins have heme as their prosthetic subunit; these are known as hemoproteins.
