CHE113 Forensic Science Nicolas Canel Forensic Serology Blood Chemistry -Proteins can form shapes such as helicies and sheets. This is a close-up of part of an alpha helix in a hemoglobin protein chain. Hydrogen bonds are weak electrostatic (+ attracts -) bonds between H and O. Blood Chemistry -Molecular model of hemoglobin with the subunits displayed in the ribbon representation. A ribbon representation traces the backbone atoms of a protein and is often used to represent its three-dimensional structure - Alpha-helix structure in a subunit of hemoglobin. The blue strands are a ribbon representation to emphasize the helical structure. The green dotted lines show the hydrogen bonding between the -NH and -CO functional groups. -Three-dimensional molecular model of heme coordinated to the histidine residue of the hemoglobin protein. Above is a two-dimensional drawing of heme coordinated to the histidine residue. In this figure, the protein is deoxygenated. -Change in shape of the heme group from the deoxygenated to the oxygenated form.
