The Sequence Decides Everything
You'll learnhow a protein's amino-acid sequence folds it into a working shape, and why the peptide bonds survive denaturation.
A protein begins as a list — amino acids in a fixed order — and folds through four levels of structure into a shape that does a job. The sequence decides the fold, the fold decides the function, and heat can take the shape without ever touching the sequence. Twelve short steps; press Next for each one.
a list folds into a shape · the shape is the job

What you're looking at
Ten amino-acid beads joined by nine peptide bonds, read N to C. A real protein has hundreds of residues; ten is just the legible number.
The question
How does a list of amino acids become a folded shape that does a job?
