    Heavy water (deuterium oxide, 2 H 2 O, D 2 O) is a form of water that contains a larger than normal amount of the hydrogen isotope deuterium (2 H or D, also known as heavy hydrogen), rather than the common hydrogen-1 isotope (1 H or H, also called protium) that makes up most of the hydrogen in normal water. The presence of deuterium gives the water different nuclear properties, and the

    Disulfide bonds tether different regions in a protein and thereby compact its three-dimensional structure. Such compacting inhibits the ability of proteases to access all possible cleavage sites, leading to incomplete digestion. As such, proteins with disulfide bonds may be reduced and alkylated prior to enzymatic digestion in order to enhance the efficiency of cleavage. One must remember
