So we essentially extract two electrons from this particular glucose phosphate and those two electrons are picked up by this molecule. In addition, an H ion is picked up by this molecule as well. And we generate the reduced version of nicotine amide adenine Dinucleotide phosphate. We also release the H plus ion and we produce the six phosphoglucano delta lactone molecule. So this is essentially an Esther bond that we form. And so this is known as an intramolecular estermolecule.
