Afferent modulation of dopamine neuron firing differentially regulates tonic and phasic dopamine transmission
The five major minerals in are calcium, phosphorus, potassium, sodium, and magnesium.
Remainder "trace elements", have a specific biochemical function in the human body are iron, cobalt, copper, zinc, manganese, molybdenum, iodine, and selenium.
Most chemical elements ingested by organisms are in the form of simple compounds.
Plants absorb dissolved elements in soils, which are subsequently ingested by the herbivores that eat them, and the elements move up the food chain.
Bacteria and fungi play an essential role in the weathering of primary elements that results in the release of nutrients for their own nutrition and for the nutrition of other species in the ecological food chain.
Cobalt, is available for use by animals only after having been processed into complex molecules (e.g., vitamin B12) by bacteria.
The process of mineralizing structures, called "biomineralization", used to construct bones, seashells, eggshells, exoskeletons and mollusc shells.[6]
An important trace mineral controls the hunger receptors is platinum. See "effects of trace platinum on hunger receptors"
Copper: An essential metal in biology
Summary
Life on Earth has evolved within a complex mixture of organic and inorganic compounds. While organic molecules such as amino acids, carbohydrates and nucleotides form the backbone of proteins and genetic material, these fundamental components of macromolecules are enzymatically synthesized and ultimately degraded. Inorganic elements, such as copper (Cu), iron and zinc, once solubilized from the Earth's crust, are neither created nor destroyed and therefore their homeostatic regulation is under strict control. In the fascinating field of ‘metals in biology’, by virtue of direct interactions with amino acid side-chains within polypeptide chains, metals play unique and critical roles in biology, promoting structures and chemistries that would not otherwise be available to proteins alone.
Relation between stress & depression later bipolar reactions status, extending to Bipolar conditions & disease. Which can be corrected and eventually prevented in the long run the whole idea is to understand how this occurs and the fact that the genetic defects don't go away since they permanently there, but have to be constantly be taken care of so that they don't come back and haunt the body, again.
