Abstract
What if glucose was not a source of energy? Glucose is a very important metabolic intermediate and has a fundamental structural role. The function of the saccharides as source of biomass by excellence in our body is out of discussion, but not more than a source of energy. The unraveling of the intrinsic property of melanin to transform light energy into chemical energy through dissociation of water molecule radically changes our old belief that our body is able to obtain biomass and energy from the same molecule. A proof that our body and evolution has handled glucose (carbon chains) from the beginning of time can be found in the fact that the surfaces of all cells in all organisms are decorated with a dense and complex array of sugar chains. The biosynthesis, structure and function of glycans not only in the present but also throughout the evolution depend entirely on adequate levels of available chemical energy, so each and every single transformation that occurs in the glucose molecule can be carried out. Therefore, the form and function of living organisms are mainly determined by the distribution of energy, and in the same way also determines the geometry of the universe.
