Detailed explanation-1: -An amino acid is an organic molecule that is made up of a basic amino group (−NH2), an acidic carboxyl group (−COOH), and an organic R group (or side chain) that is unique to each amino acid.
Detailed explanation-2: -The key elements of an amino acid are carbon, hydrogen, oxygen, and nitrogen. They are particularly important in biochemistry, where the term usually refers to alpha-amino acids. Amino acids serve as the building blocks of proteins, which are linear chains of amino acids.
Detailed explanation-3: -At the “center” of each amino acid is a carbon called the carbon and attached to it are four groups-a hydrogen, an -carboxyl group, an -amine group, and an R-group, sometimes referred to as a side chain.
