A biochemist was studying a protein produced by a bacterium that can grow in very hot water. He discovered that this protein would not precipitate in boiling water unless he added some B-mercaptoethanol (also known as 2- mercaptoethanol or BME).

b. Suppose you bubbled oxygen extensively through a 0.1 M solution of B-
mercaptoethanol. Once this reaction had reached completion, what would be the
major carbon-containing products of the reaction? Write appropriate structures.
