What is the Chemical equation for bread?

White or wheat?

A white bread...

I'm not sure what you mean by chemical equation, something like flour isn't exactly a consistent chemical.

I just need the chemical equation of a common bread.
Like we were experimenting, then we heat a piece of bread gently inside the test tube. Then we need to get it's equation..

It's going to be mostly organic compounds. Carbon, Oxygen, Hydrogen, maybe a little Nitrogen.

I think the equation you will be looking for will be a energy one not a chemical one. Do you have to find out how much energy was in the bread? What did you do in the experiment exactly?

Or go to the molecular level?
You're re-heating backed bread(?) in a tube and want to calculate the results?
Or, raw dough? Risen or unrisen..
See, there are still, too many variable.
Perform your experiment and report back the results.

You can compare your experimental result with the result on the packet, if it's a commercial bread. It should be in the nutritional information.

Any difference between the values will be differences in experimental technique (mostly)

We are experimenting the presence of water, so we heated the plain white bread until it produces moist. So I need the equation of the heated plain bread, because there's a question in our lab manual that asks us to write the chemical equation for the plain white bread and I didn't know what it's chemical equation...
so I need the reactants and products..

Example:
as the brown sugar heated, it melted.

Equation:
C6H12O6(solid)---->(heating process) 12C + 11H2O(aqueous)
