The Fahrni group pioneered cellular detection of this element using tetrathiazacrown (“tetra-THY-uh-za-crown”) ether probes. This metal is needed for beta-monooxygenases to convert dopamine into norepinephrine. This metal can be delivered to its ATP7A transporter while bound to ceruloplasmin. (10[1])This metal’s iodide is notably not required when using cyclooctynes (“cyclo-OCK-tynes”) developed by the Bertozzi group in a variant of click (10[1])chemistry “free” of it. (10[1])Zinc and this (10[1])metal are coordinated in the most common family of eukaryotic superoxide dismutases. (10[1])ParaGard is among a class of IUDs coated in this metal. (10[1])Epoxide (10[1])ring openings (10[1])in alkaloid syntheses often use lithium and this metal in the form of Gilman reagents. Oxygen is bound to this metal in hemocyanin giving spider blood a blue hue. For 10 points, name this element whose symbol is Cu. ■END■
