How Amino Acids Are Made

Amino acids are made from plant-derived ingredients. Fermented products such as miso and soy are made by fermenting soy or wheat with a koji culture. The fermentation process breaks down the protein and turns it into amino acids.

How are amino acids made from DNA?

In the genetic code, each three nucleotides in a row count as a triplet and code for a single amino acid. So each sequence of three codes for an amino acid. And proteins are made up of sometimes hundreds of amino acids.

How are proteins produced?

To build proteins, cells use a complex assembly of molecules called a ribosome. The ribosome assembles amino acids into the proper order and links them together via peptide bonds. This process, known as translation, creates a long string of amino acids called a polypeptide chain.
