Heating of sugar

Beginner - 22-2-2014 at 01:46

Hi! I wonder, if I heat sugar slowly, which is all the chemicals I get, before all becomes to coal and carbon dioxide? And does the process has any similaritys to the combustion of sugar in the human body? (Sorry for the English, I'm from Sweden.) This is no schoolwork, I'm just curious.

Here is a thread about dry distillation of sucrose.

Also, take a look at the following PDF regarding the pyrolysis products of sucrose.

Thanks! Concerning if the decomposing of sugar by heat has any similaritys with catabolism of sugar in the human body, is there anyone who knows? Thus, if it decomposes to the same products?

If you heat it, it becomes coal (carbon) and steam (H2O). No carbon dioxide unless some of the carbon burns in the air.

It is not similar to the catabolism of sucrose. Sucrose is first broken down into fructose and glucose (by invertase). Then, the glucose undergoes glycolysis and the fructose undergoes a similar process. Eventually, both are converted to pyruvate for use in the Krebs cycle.
