Kenneth Dill, right, and co-authors Adam de Graff, left, and Michael Hazoglou, center, standing beside a computerized display of three identified proteins at risk for oxidation: (Left) – A normal protein that has a balance of charges not at risk for oxidation; (Center) – The RBAp48 protein is at risk because of a high negative charge (red area), which are histones known in memory loss. (Right) – Telomerase protein is at risk for oxidation because of high net positive charge (blue area).
