How are Proteins and Amino Acids made?

Protein supplements are made from naturally synthesized proteins found in egg, soy or other foods. These are then processed to yield the protein found in them. Making a protein is very expensive based upon how much raw materials are wasted to give very little desired product because of the steps to add an amino acid to a chain of amino acids. To make a free amino acid though is fairly simple in comparison to a protein. Amino acids can be made from easy organic chemistry substitution addition reactions from naturally occurring precursors.
