Amino acids are characterized by their central carbon atom, known as the α-carbon, which is bonded to an amino group (-NH2), a carboxyl group (-COOH), a hydrogen atom, and a variable side chain ...

carbon atom linked to an amino group, a carboxyl group, a hydrogen atom, and a variable component called a side chain (see below). Within a protein, multiple amino acids are linked together by ...

Originally, many of the sample types analyzed in the lab were mollusks, but now include bird eggshells, algal remains, synthetic amino acids, and more. Originally, many of the sample types analyzed in ...

Chemically, an amino acid is a molecule that has a carboxylic acid group and an amine group that are each attached to a carbon atom called the α carbon. Each of the 20 amino acids has a specific ...
