I got a question wrong a my biology exam that I think is right. My teacher did not let us take the exam home and I don’t remember the exact wording but:

In a DEHYDRATION REACTION, there is a loss of a water molecule. I know this to be true from my studying and from a quick google search. However, the water molecule that is lost, will it be taken away from the end product of what is created?

For example, say that C6,H8,O4 binds to another C6,H8,O4 with a dehydration reaction. (numbers are subscripts, I can’t type subscripts here)

Will the result be C12,H16,O8 or will it be C12,H14,O7 because 1 water molecule is lost due to the dehydration reaction?
