This creates a double bond between the substrate carbon and the TPP carbon and pushes the electrons in the N-C double bond in TPP entirely onto the nitrogen atom, reducing it from a positive to neutral form. In what is essentially the reverse of step one, the TPP-substrate bond is broken, reforming the TPP ylid and the substrate carbonyl.

A full view of TPP. It achieves this in four basic steps: The TPP thiazolium ring can be deprotonated at C2 to become an ylid. 2. TPP also goes by the name thiamine diphosphate. In what is essentially the reverse of step two, the electrons push back in the opposite direction forming a new bond between the substrate carbon and another atom. This cycle breaks fatty acids, amino acids and monosaccharides into smaller molecules that produce adenosine triphosphate (ATP) energy within your mitochondria. Thiamine is a water-soluble vitamin having a critical role in glucose metabolism. I did not notice much of a difference one way or the other, but was just taking it as a preventive measure.
