Protein Primary Structure
Captions available
The idea
A protein's primary structure is the specific linear sequence of amino acids joined by peptide bonds along its chain.
In practice
Changing even one amino acid in a chain of hundreds can change the protein's primary structure enough to change how it folds.
Where people slip
Primary structure names only the sequence, not the three-dimensional shape that sequence goes on to fold into.
