Provide history of amino acids?


Amino acids are the building blocks of proteins, which play essential roles in the structure and function of all living cells. Amino acids are small organic molecules that contain an amine group, a carboxyl group, and a side chain that is unique to each amino acid. There are 20 naturally occurring amino acids, each with a specific chemical structure and properties.

The discovery of amino acids dates back to the early 19th century, when they were first isolated from proteins. In 1806, French chemists Louis Nicolas Vauquelin and Pierre Jean Robiquet isolated asparagine, an amino acid found in asparagus, from asparagus juice. In 1819, Swedish chemist Jöns Jacob Berzelius isolated cystine, an amino acid found in animal proteins, from the protein keratin.

In the early 20th century, scientists began to study the chemical structure and properties of amino acids in more detail. In 1901, Emil Fischer proposed the “lock and key” model of enzyme action, in which enzymes bind specifically to their substrates, similar to how a key fits into a lock. This led to the discovery of the peptide bond, which is the chemical bond that holds amino acids together in a protein chain.

In the decades that followed, scientists made important discoveries about the role of amino acids in living organisms. They found that amino acids are necessary for the synthesis of proteins and enzymes, and that they play important roles in metabolism, energy production, and many other physiological processes.

Today, amino acids are widely used in research, medicine, and industry. They are often used as supplements to support muscle growth and repair, and they are also used in the production of food, cosmetics, and other products.
