such as integral membrane proteins, transcription factors or strongly acidic proteins. To circumvent these limitations we developed a flexible screening system, called the DUALhunter system ...

TRICHLOROACETIC acid (TCA) is widely used as a protein coagulant in the preparation of protein-free sera; but there is little information concerning its mode of action. Rowland 1 has shown that ...

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 ...

where they block acid production. Researchers at the German Cancer Research Center (DKFZ) made the surprising discovery that ...

Research indicates that incorporating phosphatidic acid as a supplement can augment muscle protein synthesis, boost strength and power, and enhance an individual’s overall physical well-being.

This depends on the type of enzyme. The enzyme pepsin breaks down proteins in the acidic conditions of the stomach. Pepsin has an optimum of pH 2.5 and a working range of between pH 1-4.

Proteins have four levels of structure: primary (amino acid sequence), secondary (local folding patterns like alpha helices and beta sheets), tertiary (overall 3D shape), and quaternary (assembly of ...
