Amino Acids Are Also Known As The "Building Blocks Of Life". Proteins (From The Greek Word "Protos", Meaning "First" Or "Most Important"), Are Some Of The Most Important Building Blocks Of All Living Things. Protein Building Blocks Are Better Known As Amino Acids. They Can Be Found As A Raw Material In Cells And Muscle Tissue. They Are Important For Internal Organs, Bones, Skin, Hair, Growth, And For The Maintenance And Regeneration Of Cells. They Direct Chemical Processes, Supporting The Production Of Enzymes And Hormones. They Also Play An Important Role In The Immune System. What Exactly Are Amino Acids? In The Human Body, 23 Protein-Building Amino Acids Have Been Discovered So Far. Other Amino Acids Are Important For Human Metabolism Without Being Used For Protein Production. Eight Of Them Are Essential For Humans, Which Means That They Cannot Be Produced By The Body And Must Be Acquired From Food. In Some Circumstances, Even Non-Vital Amino Acids Can Be Essential. It Has Been Proven That Some Amino Acids, Although They Are Not Important For Survival, Greatly Increase Bodily Performance. These Amino Acids Are Classed As Semi-Essential, And For This Reason They Have Come To Play An Important Role In Nutritional Supplements. As Well As Their Functions In Protein Construction, Amino Acids Are Important For A Large Number Of Metabolism Processes: They Are Precursor Molecules To Biologically Important Substances Such As Hormones, Vitamins And Functional Building Blocks. In Conjunction With Other Substances, They Play A Role In Directing Important Brain Functions. They Also Influence The Complicated Hormone System To Carry Out Anabolic (Muscle-Building) Functions. Detoxifying Metabolic Processes Are Also Influenced By Amino Acids. They Function As "Emergency Energy Sources" To Cells For The Control Of The Acid-Alkali Balance, Especially In Situations Involving Extreme Exertion.
