combustion of glucose
« on: August 30, 2004, 09:59:16 PM »
can you please help me determine the hypothetical balanced equation of the combustion of glucose (aerobic) into lactate acid.

C6H12O6 + O2 ----------> CH3CH(OH)COOH ?

Thanks

In living organisms glucose is transformed into lactic acid without need of oxygen
(anaerobic process)
C6H12O6  ----------> 2CH3CH(OH)COOH

Direct chemical oxidation of glucose to lactic acid is impossible since need rearrangement of carbon-oxygen bonds. In this way only oxalic acid can be obtained.

Also, the hormone insulin plays a HUGE role in the breakdown of glucose.  I'm not 100% sure if it just helps move the glucose molecule into the cells of body, or if it plays a role in holding the glucose molecule while other reactions occur, but without it you have a problem.  (Being a diabetic, I should know.   :P)  Without insulin, the body will get its energy from another source which would be the breakdown of fats into ketones.

Did you mean the overall equation for anaerobic respiration for the oxidation of glucose to lactic acid?
