Question
Cysteine (above in Pb question) is the action stop in glutathione. Give the equilibrium reaction between the oxidized and reduced forms of GSH and GSS, drawing only the species involved in the dimerization (ie only worry about the cysteine bit). Which side does the equilibrium lie on?
Show the reaction of GSH with H2O2, giving the oxidation states of any species that change oxidation states in the reaction.
Question7. Which of the following amino acids would Pb Why? most likely interact with? H2N-CH-C CH2 CH CH2 SH OHExplanation / Answer
The Pb2+ ion resembles to the Ca2+ and Zn2+ ions in our body. Due to their positive charges these ions need negative charged amino acids or cysteine and methionine amino acids. Therefore, Pb2+ will bind to Aspartate and Cysteine. However, it most likely binds with Aspartate.
