Bridges of this element are created in polymers in vulcanization.
This element and oxygen bond to molybdenum in the center of xanthine oxidase, and it binds to another metal in the P cluster of nitrogenase. This element can be added to organic compounds using Lawesson's reagent. Alcohols can be prepped for SN2 reactions by converting them into a better leaving group containing this element known as a tosylate. This element, which bonds to (*) iron in aconitase and the ferredoxins, is typically found as an orthorhombic crystal containing 8 atoms of it. This atom is replaced with selenium in an alternate version of cysteine. Bridges of this element are created in polymers in vulcanization. For 10 points, name this element which bonds to carbon in a thiol which is known for its bright yellow color and is symbolized S.
