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 ...

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 ...

Amino acids are small molecules that are the building blocks of proteins. Proteins serve as structural support inside the cell and they perform many vital chemical reactions. Each protein is a ...
