Secondary Structure of Proteins
The nature of the bonds in the peptide backbone plays an important role here. Within each amino acid residue are two bonds with reasonably f...
Tertiary Structure of Proteins
The tertiary structure of a protein is the three-dimensional arrangement of all the atoms in the molecule. The conformations of the side cha...
Quaternary Structure of Proteins
Quaternary structure is the final level of protein structure and pertains to proteins that consist of more than one polypeptide chain. Each...
Protein-Folding Dynamics
We know that the sequence of amino acids ultimately determines the three-dimensional structure of a protein. We also know that proteins can...
