WebAcetylcysteine is used intravenously as an antidote for severe paracetamol poisoning, in which it acts as a thiol donor. Oral acetylcysteine has been investigated for the treatment of cancer. Acetylcysteine 600 mg/day was compared with retinol 300 000 U/day, the combination, and a placebo in a total of 2191 patients treated for 2 years. Adverse ... Thiols having the structure R−SH, in which an alkyl group (R) is attached to a sulfhydryl group (SH), are referred to as alkanethiols or alkyl thiols. Thiols and alcohols have similar connectivity. Because sulfur atoms are larger than oxygen atoms, C−S bond lengths – typically around 180 picometres – are about 40 picometers longer than typical C−O bonds. The C−S−H angles approach 90° whereas the angle for the C−O−H group is more obtuse. In solids and liquids, the h…
