Thiamine in Biological Technology

New uses for imidazolium salts in medicine and alternative energy

... cellular system, thus attenuating the effects of ROS. IMS is a precursor for N-heterocyclic carbenes (NHC). A naturally occurring form of NHC is thiamine or vitamin B, which plays a very important biological role. Vitamin B deficiency has been linked to oxidative stress. While natural antioxidants such ...

Kinetic determination of vitamin B1

... the technique is applied to the determination of thiamine (vitamin B 1 ) in solution. Fluorescence intensity is monitored as thiamine converts to fluorescent thiochrome, and a ... preparations to quantify non-fluorescing thiamine (vitamin B 1 ), which oxidizes to fluorescent ...
