Etymology
Back-formation from hemoglobin.
Pronunciation
Noun
heme (countable and uncountable, plural hemes)
- (biochemistry) The component of hemoglobin (and other hemoproteins) responsible for binding oxygen. It consists of an iron ion that binds oxygen and a porphyrin ring that binds the globin molecules; one molecule binds one molecule of oxygen.
- 2008, John Greer, John Foerster, George Rodgers, Fixos Paraskevas, Bertil Glader, Daniel Arber, Robert Means Jr, Wintrobe's Clinical Hematology: Volume One: Twelfth Edition, page 141:
- The binding of oxygen to the iron molecule causes the hemoglobin molecule to undergo conformational changes that affect the binding of oxygen to other heme sites.
2018, Ruth Reichl, Silvia Killingsworth, The Best American Food Writing 2018, Mariner Books, →ISBN, page 152:Impossible's breakthrough was in discovering that meat's essence comes from heme—the iron-rich molecule in blood that carries oxygen and is responsible for the deep-red color.
