- Protein: SHAYNERSE Predict the products of the following reactions with the protein given, if there is none, write NO RXN. Hg/HNO3 HNO3Many biochemical reactions utilize cationic imines (a Schiff base) as electron sinks. Illustrate your understanding of this concept by drawing the mechanism of basic imine formation between an aldehyde (RCHO) and an amine (RNH2). For full credit, you must show all electron flow (using the arrow convention).4.4 Show how the compound thiodiazine - C21H26N2S2 - decomposes anaerobically and how these end products in turn decompose aerobically to stabilized sulfurand nitrogen compounds.
