Bisulfite test reaction mechanism
WebSchiff’s test is a chemical test used to check for the presence of aldehydes in a given analyte. This is done by reacting the analyte with a small … 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.

WebThe reaction of bisulphite with formaldehyde forms hydroxymethylsulphonate (HMS), which is very stable under normal conditions (temperature, pH), and has very little biological activity. WebFlorence Mauger, Jean-François Deleuze, in Prognostic Epigenetics, 2024. 2.1.1 Bisulfite and oxidative bisulfite conversion. In the bisulfite reaction, cytosine bases are deaminated to uracil bases whereas 5-methylcytosine and 5-hydroxymethylcytosine bases are not converted by sodium bisulfite under specific conditions [24–27].Several commercially …
