Amino acids are characterized by their central carbon atom, known as the α-carbon, which is bonded to an amino group (-NH 2), a carboxyl group (-COOH), a hydrogen atom, and a variable side chain ...

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 ...

In chemistry, an amino acid is a molecule that contains both amine and carboxyl functional groups. In biochemistry, this term refers to alpha-amino acids with the general formula H2NCHRCOOH, where ...

The R group gives each amino acid its unique properties. It’s what separates each of the 20 amino acids. When amino acids connect together, they fold together in 3D shapes.

An amino acid’s structure consists of a central carbon atom attached to a hydrogen, an acidic carboxyl group (−COOH), an amino group (−NH2) and an organic side chain (also called an R group). The side ...

Elongation, a crucial step in the translation process of protein synthesis, gets disrupted by amino acid sequences with an abundance of N-terminal aspartic and glutamic acid residues in eukaryotic ...
