Lactate thiamine

Webthe lactate can be converted back to glucose in the liver. Basal lactate production is approximately 0.8 mmol/kg body weight/hour. The average normal arterial blood lactate level is approxi-mately 0.620 mmol/L and the venous level is slightly higher at 0.997 mmol/L,3 but overall, arterial and venous lactate levels correlate well. WebResults: Thiamine exhibited a lower IC50 value in both cell lines compared with DCA. Both thiamine and DCA reduced the extent of PDH phosphorylation, reduced glucose consumption, lactate production, and mitochondrial membrane potential. High-dose thiamine and DCA did not increase ROS, but increased caspase-3 activity.
