For the most part, amino acid sequences can be slightly different, but sometimes a change in the sequence can have a large impact. For example, in sickle cell anemia, glutamate 6 in the beta chain is mutated to valine, resulting in a structural change that allows hemoglobin to stick to each other and create stiff fibers, which creates the sickle shape in blood cells. | For the most part, amino acid sequences can be slightly different, but sometimes a change in the sequence can have a large impact.

Each individual chain has a heme group that has an iron atom that allows oxygen to bind. Of the chains, two are beta chains and two are alpha chains. | + | Hemoglobin is made of four protein chains.
