Two of Dr. Jose Cerda’s research students won awards at the Philadelphia American Chemical Society Section 12th Annual Student Poster Session on Thursday, February 23, 2012 at Temple University. Emily Amendola ’12 and Michael Gallagher ’12 won third place and honorable mention, respectively, for their research poster presentations. Emily’s poster, entitled “An Electrochemical Method used for Probing the Interactions between Distal Residues and a Heme-Bound Fluoride in Heme proteins” reported on the pH dependence of the midpoint potential of horseradish peroxidase (HRP) in the presence of fluoride. Michael presented a poster entitled “An electrochemical study of heme-pyridine and heme-saffranine interactions”. Michael’s research was focused on using a compound called hemin to model the interactions creating free heme. Hemin is an iron-porphyrin ring with a chloride ion bound to the iron and tends to aggregate in solution, so an organic solvent that can help dissolve and displace aggregated heme would be best for creating six- coordinate heme.
