Proteins are essential macromolecules that play a crucial role in virtually all biological processes. They are the building blocks of life, performing a wide range of functions within organisms, from ...

Protein folding is a process by which a polypeptide chain folds to become a biologically active protein in its native 3D structure. Protein structure is crucial to its function. Folded proteins are ...

The enormous progress over the past decade in analytical techniques to study large macromolecules has revealed a much greater diversity in protein primary structure than predicted based on the use of ...

As people around the world marveled in July at the most detailed pictures of the cosmos snapped by the James Webb Space Telescope, biologists got their first glimpses of a different set of images — ...

What is the difference between incomplete vs complete proteins? It all comes down to amino acids—the building blocks of protein. “Your body can make [non-essential amino acids]. But the essential ...

Proteins are made of amino acid chains, or polypeptides. Amino acids have a basic backbone made of an amino group and a carboxyl group, and differ in their side-chains. These polypeptide chains of ...

A new study by chemists shows that X-ray crystallography, the standard method for determining the structure of proteins, can provide inaccurate information about membrane proteins, which in turn could ...
