What are Amino Acids?

To bring the blessings of the earth and the very essence of life to more people, we develop amino acid-based personal care ingredients friendly to people and to the earth. It's no exaggeration to call amino acids “earth-friendly.” Amino acids are natural materials, born of Mother Earth from the very essence of life, and closely related to human physiological functions. Earth-friendly and human-friendly, amino acids have many benefits yet to be explored. The first to market amino acids, Ajinomoto Co., has been a pioneer in personal care ingredients using amino acids, and is committed to exploring the virtually limitless performance characteristics of amino acids and to applying what we learn to the development of ever more beneficial personal care ingredients and products.

The earth and amino acids

When and where did amino acids come from?
Answering this question touches on the origins of the earth.
Amino acids first formed some four billion years ago.
Water, ammonia, methane, and other substances combined while the planet was still young and temperatures were much higher than today.

Amino acids concentrated in tidal pools were transformed into proteins, while base compounds became nucleic acids. These continued to evolve, ultimately leading to the beginning of life. It's no exaggeration to call amino acids earth-friendly. They are natural materials born of Mother Earth.

Life and amino acids

Amino acids are called the source of life for good reason. Our bodies' muscles, organs, skin, and hair are all made up of proteins, which are in turn made up of unique combinations of 20 types of amino acids. In the body, amino acids are converted through various metabolic pathways to a multiplicity of useful substances. As the very essence for maintaining life, amino acids are naturally human-friendly.
