thiol

But it does have an amine group and a thiol group, and can form complexes with heavier metals.

The resulting thiol group should be protected with an alkylating agent to prevent it from being reoxidized.

NAC has a free thiol group (R-SH), which can break dithiol bonds (RS-SR) in mucus to help thin it out.

Additionally, the paper mentions that the C-terminal cysteine (C12) was synthesized as a free thiol.

I know they add a thiol (sulfur compound that smells like rotten eggs) to the city mains for cooking/heating gas.

During my masters thesis I worked in the lab of an electrochemist studying the adsorption of thiol(ate)s on precious metal surfaces.

This means that it has a surrounding lipid so microscopic balls containing the difficult to absorb substance (especially any thiol-containing molecular compounds) like Glutathione, can make it past without other peptides inhibiting its absorption.

Most of these require cysteine or glutathione, for the thiol.

> natural gas furnace literally is a controlled blast of explosive gas without a smell OT: in Europe, a thiol is added to natural gas to give it a distinctive smell.

Because we burn a lot of that - even if you only add a few ppm thiol to natural gas, that's a whole lot of sulfur being burnt...

It killed 295 students and teachers, and led to the inclusion of smelly thiol in natural gas, as well as the Texas Engineering Practice Act.

So I guess that the bacteria just rarely uses Sulphur-Sulphur (thiol) bonds in it's proteins, since Arsenic has a high affinity for it (and that's what causes arsenic toxicity in everything else).
