- Heme: a complex red organic pigment containing iron and other atoms to which oxygen binds
- A heme (American English) or haem (British English) is a prosthetic group that consists of an iron atom contained in the center of a large heterocyclic organic ring called a porphyrin. ...
- The component of haemoglobin responsible for binding oxygen, consists of an iron ion that binds oxygen and a porphyrin ring that binds the globin molecules; one molecule binds one molecule of oxygen
- A pigment which contains iron and porphyrin.
- Used at the beginning of words to mean blood, e.g. haemorrhage (bleeding) haemophilia (inherited disorder in which blood clots very slowly).
- Compounds of iron complexed in a porphyrin (tetrapyrrole) ring that differ in side chain composition. Haems are the prosthetic groups of cytochromes and are found in most oxygen carrier proteins.
- Or haema- or haemo- See: hem-.
