My Campbell's Biology 9th edition textbook says that a dehydration synthesis is a reaction in which water is produced while two monomers are joined together. Specifically, it makes the following statement:
One monomer provides a hydroxyl group (-OH), while the other provides a hydrogen (-H).
Sorry if this is a silly question to ask, but what I'm wondering is how exactly a Hydrogen electron joined with a Hydroxyl will create H2O? Why isn't it a Hydrogen atom (1 proton and 1 electron) rather than just the electron which moves?
