WebReaction between ascorbic acid and nitrous acid is effective in eliminating a carcinogenic nitrosamine, N-nitrosopyrrolidine, created during the process of frying in bacon. As the nitrosamine is formed in adipose tissue, fat-soluble ascorbyl palmitate is noted to be better suited than ascorbic acid. WebIn the resulting molecule, what used to be the aldehyde hydrogen is now acidic - this is so because, when the proton is abstracted by hydroxide, the negative charge on the conjugate base is stabilized by resonance with the positively-charged thiazole ring of thiamine. paisano\u0027s chantilly va
