They play a crucial role in the structure, function, and regulation of the body's tissues and organs. Amino acids are characterized by their central carbon atom, known as the α-carbon, which is bonded ...

The catalytic site of chymotrypsin contains an interior aspartic acid hydrogen-bonded to a histidine which in its turn is hydrogen-bonded to a serine. Polarization of the system due to the buried ...
