📚Inorganic Compounds📚

As stated in previous articles... bio chemistry is the study of the chemical composition .. &.. the reactions of living matter ... all the chemicals in the body fall into one of the 2-major-classes..& .. again they are Organic..&.. Inorganic compounds.. 

As state in the previous articles... water is the most abundant.. &.. important inorganic compound in living material .. making up 60 to 80% of the volume..  of most of the living cells.. 

📚Bio chemistry is a wet chemistry ... 

Biological molecules do not react chemically .. unless they are in a solution.. &.. basically.. all the chemical reactions occurring in the body depend on the waters solvent properties .. So... we also need to discuss the.. 

📚Salts .. 😇

A salt .. is a ionic-compound containing Cations.. &.. Anions..

😳Omg🤗.. ⁉️What is a Cation.. &.. Anion 😳☹️⁉️.. you ask.. 

😎📚 The answer is.. a cation.. is a Ion.. with a Positive-Charge .. &.. the Anion..  is a Ion carrying one or more negative charges.. &.. so.. it is attracted to a positive-pole.. 

I am hoping I mentioned it .. but .. if I did not.. when a salt dissolves in water ... they disassociate into their .. component Ions... example sodium sulfate(NA2SO4).. disassociates into two.. Na+ Ions.. &.. SO4-2.. 

This ability to easily disassociate is because ... the Ions are already formed... all that is necessary to be done .. is for water to overcome ... the attraction forces.. between the oppositely charged ions.. 

Electrolytes.. are Ions.. 😳Do you want a better description🤔⁉️... okay 🤗.. 

📚.. electrolytes are substances that conduct a electrical current in a solution.. I must include here as well.. that groups of atoms can carry a overall charge... such as sulfate.. &.. of course .. they have a name as well.. &.. that is.. Polyatomic-Ions.. 

The Salts.. that are commonly found in the body include.. NaCl-Sodium Chloride.. CaCO3-Calcium Carbonate.. &.. KCl-Potassium Chloride.. but.. The most abundant salts that are within the body .. are the Calcium Phosphates ... that are making the bones.. &.. teeth hard.. 

📚When salts.. are within their ionized form.. they play a huge role in bodily functions... for instance the electrolyte properties of sodium.. &.. potassium ions .. well.. they are extremely important for nerve function .. specifically nerve impulse transmission.. &.. muscle contraction.. 

📚To explain ... 

Sodium is the main positive charged within the extracellular fluid .. the fluid outside the cell.. &.. potassium is the main positive charge within the cell.. the intracellular fluid.. 

📚Sodium is ⚡️action-potential⚡️.. during a nerve impulse transmission.. sodium rushes into the cell.. let us say a muscle cell.. when acetylcholine .. A neurotransmitter .. opens .. the sodium ion channels.. 

💥As sodium enters into the cell💥 this changes the polarity of the cell .. to a more positive state .. creating .. the ability for the cell to do work🏃‍♀️.. however this must be reset.. 

Which is bringing the cell... down to a more negative state .. a resting 💤state.. this is the job of the sodium potassium ion pumps.. which are... membrane-bound-protein-pumps.. &.. they do this by pumping 3-sodium ions .. out of the cell into the extracellular fluid .. while .. also... pumping 2-potassium ions .. into the cell .. 

This shift in... ion concentration... alters the polarity of the cell... as three positive charges ... are leaving/going out of the cell.. &.. only 2-positive charges are entering the cell.. 

I should mention .. as well .. that the negatively charged proteins .. within the cell never leave.. this is why the concentration change here... is only through the positive charged ions .. which are the sodium.. &.. potassium.. as to mention again .. sodium is the main positive charge in the extracellular fluid .. outside the cell.. &.. potassium is the main positive charge inside the cell.. 

⁉️😳Do you think I am done.. Nope.. 😇.. 

Most of us have heard of .. hemoglobin.. well .. what is is exactly😳⁉️.. Hemoglobin.. is a Protein .. that makes red blood cells ... red... &..  binds.. well as ... reversibly with oxygen .. &.. most oxygen that is carried through the blood ... is bound to Hemoglobin.. 

hemoglobin is made up of the red heme pigment.. bound to the protein globin.. 

📚Globin.. Consisting of 4-polypeptides chains .. binding .. to a ring like heme group.. 

Ionic Iron forming part of the hemoglobin molecules ..&.. helping to transporting oxygen within the red blood cells.. 

I hope..  I am getting across to you the .. importance of maintaining the proper ionic balance within our bodily fluids .. Ionic balance..  is one of the most important homeostasis-static.. which is job of balance within the body .. 

A perfect example of this is the role of the kidneys.. 

When this balance becomes severely disturb ... nothing .. in the body is going to work well... &.. thousands of physiological functions can be possibly even ... stopped..
