Thiamine is a cofactor for enzymes required in:
Krebs cycle
Pentose phosphate pathway
Alpha-ketoglutarate dehydrogenase
Pyruvate dehydrogenase.
Because thiamine is an important cofactor in critical pathways for energy production, deficiency results in lactic acidosis and alteration of brain metabolism.
Thiamine is also important for lipid metabolism and may affect myelin sheath formation. This may explain peripheral neuropathy symptoms in dry<unk> .
