Definition

A type of protein found in red blood cells that binds with iron and carries oxygen throughout your body.

Etymology

From Latin 'globus' (sphere/ball), referring to the compact, roughly spherical shape of this protein molecule. Coined in the 19th century as biochemistry developed.

Kelly Says

Hemoglobin—the iron-carrying protein in your blood—is made of four globin chains linked together, and a single red blood cell can contain 280 million hemoglobin molecules working simultaneously to deliver oxygen to your tissues!
