Bisulfite reaction with formaldehyde
Sodium bisulfite (or sodium bisulphite, sodium hydrogen sulfite) is a chemical mixture with the approximate chemical formula NaHSO3. Sodium bisulfite in fact is not a real compound, but a mixture of salts that dissolve in water to give solutions composed of sodium and bisulfite ions. It appears in form of white or yellowish-white crystals with an odor of sulfur dioxide. For properties of sodiu… WebJul 1, 2015 · Reaction of bisulfite with formaldehyde. The optimum experimental conditions were determined for the concentrations of FA which are lower than the linearity range of the suggested method (these concentrations were not capable for the analysis by applying the suggested method.

WebBisulfite-mediated conversion of cytosine (C) to uracil (U) occurs in three steps. The first step is the addition of bisulfite to C. This reaction occurs at acid pH. The second step is the deamination of cytidine–bisulfite (C-SO 3 −) to produce uracil–bisulfite (U-SO 3 −), which is optimal at a pH of 5 to 6.
