Jamal Salah and Vishwa Shah.   We are doing deoxyhemoglobin.
Name: Jamal Salah and Vishwa Shah! 
 
LKT:
It's alpha and beta SUBUNITS (2 of each). Say something about the secondary elements (ie 5 alpha helices and 2 beta strands)
I see problems with greek letters on the JMol, so best to write out alpha and beta. Why did you highlight His which is not hydrophobic?

Haemoglobin (Hb) is an iron Fe chelate tightly binding one Fe ion in its II oxidation state where it carries the charge 2+(ferrous ion). If no oxygen molecule is bound it is called deoxyhaemoglobin. Deoxyhaemoglobin is a tetramer of two α and two β chains.The<scene name='Sandbox4/Overall_structure/1'>Overall structure</scene> of the protein-deoxyhaemoglobin!
