WebJul 31, 2024 · In more dilute acid, the rate picks up because there is more free RNH 2 in solution. Dehydration of the aminoalkanol (Equation 16-6) is acid catalyzed; this reaction normally is fast at pH values smaller than 3-4. Therefore, the slow step at pH < 4 is … WebIn 1970 two groups simultaneously described the reaction between pyrimidines and sodium bisulfate (NaHSO3, [37, 38] ). They demonstrated that treatment of DNA with sodium bisulfite results in specific deamination of cytosine and conversion into uracil. Deamination of 5-methylcytosine occurred much slower compared to cytosine deamination.
