Witryna22 sie 2024 · Leghemoglobin is a globin—one of a group of globe-shaped proteins found in animals and plants. The globin you are probably most familiar with is hemoglobin, which transports oxygen from your lungs to the rest of your body, and which gives blood its red color. WitrynaHemoglobin is the protein that makes blood red. It is composed of four protein chains, two alpha chains and two beta chains, each with a ring-like heme group containing an iron atom. Oxygen binds reversibly to these iron atoms and is transported through blood.
