- 2. Hemoglobin is a protein in red blood cells that contains iron and facilitates the transport of oxygen. The iron sits in the center of a heme ring in the form of Fe²+. The structure of a heme ring is here. H-C H-C H I H-C H H I C-N H-N-C C I C H C-N-H N-C C-H 1 C-H C-H H H a) The above structure is incomplete. Add electron pairs, non-zero formal charges, and/or additional bonds where needed to fulfill the octet rule to complete the structure. b) When Fe²+ is added to the structure in part a), the H atoms connected to the N are removed, see figure on the right. If you think of the heme ring as 4 N atoms, determine the molecular geometry of the new structure (you can draw it like [FeN4]2+). Imagine each N connects to Fe with a single bond.
