1 Rinse 3 bunches of mustard greens under water and drain them well. 2  Trim the stems of the greens and chop, if desired. 3  Boil 2 cups (474 ml) of water or broth in a pot and add the mustard greens. 4  You may need to push them down in the pot to make room. Rinse the mustard greens in cold water, drain and chop them up. 2  Place a skillet on medium heat and pour 2 to 5 tbsp. ( 3 29.58 to 73.95 ml) (in relation to the amount of mustard greens) of water or broth into the pan.
Electron acceptor and donor. Electron acceptors are ions or molecules that act as oxidizing agents in chemical reactions. Electron donors are ions or molecules that donate electrons and are reducing agents. In the combustion reaction of gaseous hydrogen and oxygen to produce water (H 2 O), two hydrogen atoms donate their electrons to an oxygen atom.
ROOR' + electron donor (2 e â) + 2H + â ROH + R'OH. For many of these enzymes the optimal substrate is hydrogen peroxide, but others are more active with organic hydroperoxides such as lipid peroxides.Peroxidases can contain a heme cofactor in their active sites, or alternately redox-active cysteine or selenocysteine residues.The nature of the electron donor is very dependent on the structure of the enzyme. 1  For example, horseradish peroxidase can use a variety of organic compounds as electron donors and acceptors.or many of these enzymes the optimal substrate is hydrogen peroxide, but others are more active with organic hydroperoxides such as lipid peroxides. Peroxidases can contain a heme cofactor in their active sites, or alternately redox-active cysteine or selenocysteine residues.
