Protein structure is the biomolecular structure of a protein molecule. Proteins are
polymers — specifically polypeptides — formed from sequences of amino acids ...
We will then use this understanding of protein structure at the atomic level to
describe how the precise shape of each protein molecule determines its function
Apr 21, 2002 ... Some aspects of protein structure can be deduced by examining the ... occurs in
a condensation reaction involving loss of a molecule of water.
The shape of a protein is determined by its primary structure (sequence of amino

Chaperones (or, molecular
chaperones) are proteins
that guide the folding of other proteins
) which ensures the correct protein structure
and functi on. Generally they work by binding to polypeptide chains at strategic locations to prevent weak-bondi... More »
The primary structure of a protein — its amino acid sequence — drives the folding
and intramolecular bonding of the linear amino acid chain, which ultimately ...
The four levels of protein structure are distinguished from one another by the
degree of complexity in the polypeptide chain. A single protein molecule may ...
Early nutritional scientists such as the German Carl von Voit believed that protein
