En fait :
- energy transformation (a coenzyme)
- synthesis if pentoses and nicotinamide adenine dinucleotide phosphate (NADPH) (also as a coenzyme) and

Regular thiamine is poorly absorbed by the digestive system. A derivate of it, thiamine di(2-methylpropionate) disulfide, has been shown to be much better absorbed. In addition, the derivate also binds to specific cells in the brain, enhancing memory and attention and also increasing muscle control and endurance. Therefore it is used by bodybuilders and other athletes during intense training.
