Haematin


Definition:

  • (n.) Same as Hematin.

Haematoin


Definition:

  • (n.) A substance formed from the hematin of blood, by removal of the iron through the action of concentrated sulphuric acid. Two like bodies, called respectively haematoporphyrin and haematolin, are formed in a similar manner.
