Definition
ChEBI: Dipropyl disulfide is an organic disulfide where the alkyl groups specified are propyl. It is a component of the essential oils obtained from Allium. It has a role as a plant metabolite.
Preparation
By boiling propyl bromide and Na2S2 in propyl alcohol; from iodine and n-propyl mercaptan; from propyl iodide and
sodium thiosulfate by way of sodium propyl thiosulfate, followed by heating.
Taste threshold values
Taste characteristics at 10 ppm: alliaceous, sulfurous, green, vegetative and asefetida nuances.
General Description
Dipropyl disulfide (DPDS) was an efficient scavenger of reactive oxygen species (ROS) at a lower concentration in both HL-60 and HepG2 cells. It prevents the oxidative DNA damage caused by N-nitrosopiperidine (NPIP) and N-nitrosodibutylamine (NDBA).
