There are 20 amino acids that make up proteins and all have the same basic structure, differing only in the R-group or side chain they have. Amino acids are in an equilibrium between two acids with ...

This description included the final step of their synthesis — the conjugation of the amino acids taurine or glycine by our liver. Almost a century later, our discovery has revealed that the ...

The sequence of amino acids in the chain determines how the chain will fold up to make the protein, so different proteins have different three-dimensional shapes. The three-dimensional shape of a ...
