Protein Building Blocks and Folding

Proteins are built from amino acids linked by peptide bonds. Long chains of amino acids are often called polypeptides, and the terms proteins and polypeptides are sometimes used the same way. In this context, polypeptides with a molecular weight below 10,000 daltons are called polypeptides, while proteins have a higher molec...

A protein is a chain of amino acids, compounds that contain amine and carboxyl groups, along with different side chains denoted as R, attached to a core carbon.

Amino acids are linked through covalent peptide bonds, and the repeating series of atoms along the core is called the polypeptide backbone.

The sequence begins at the N-ter...
