Amino acids are organic compounds that serve as the building blocks of proteins in living organisms. They contain an amine group (NH2) and a carboxyl group (COOH), as well as a side chain or "R group" that differs for each amino acid. There are 20 standard amino acids that make up the proteins in our bodies, each with unique chemical properties and functions. Research in the field of amino acids includes studying their role in protein synthesis, metabolism, and overall health. This can involve examining the structure and function of different amino acids, as well as investigating their interactions with other molecules and their effects on various physiological processes. Researchers may also study amino acid deficiencies and how they can impact health, as well as explore the potential therapeutic applications of specific amino acids in treating diseases or promoting overall well-being.
