haem
Iron-bearing blood pigment
Haem is the British spelling of heme, the iron-containing compound that gives blood its red color and enables hemoglobin to carry oxygen.
It appears in scientific and medical writing: haem synthesis, haem molecules.
The spelling extends to related terms: haemoglobin, haemorrhage, anaemia.
