Vitamins, drugs, and nutrients are path largely followed nowaday by students, try areas where few lights have been shade and try to bring some breakthrough to give yourself more challenge in biochemistry. Topics like effects of gazes and scents (odours) on health are little covered.
Since the major discovery that some gazes like nitrogen monoxide (NO) has effect on the central nervous system as well as peripherical nervous system, a third de novo way of cell communication was unveiled. For decades scientist thought that communication betwen neurons, betwen neurons and cells, or down the pipeline cell-cell communications was done only through hormones or neuro-chemicals (adrenalin, acetycholine, etc). All of a sudden they found out that simple gaz can mediate cells communications as well, opening the door to a new branch in neuronal sciences.
How does electricity convert to gazes? How can gazes which essence is expansion, something so hardly controlable, something that requires so much energy to be channeled be effective in a process so sensitive to error like cell communication? Down the road new classes of enzymes specialized in NO communication have been purified. These are the famous NOS (Nitrogen Oxyde synthases).
A world of topic to dig into. Think of all those perfumes we respire that can cause allergies. Think of cigarettes, or industrial gazes or the millions gazeous particles we know so little about. How do they affect no only physical health or mental one? On the other hand how can medecine one day use gazes and odour as mean for therapy?
