A playful intro to proteins - core of molecular biology

What if every protein
was a song?

Your body runs on proteins: tiny molecular machines behind nearly every task your cells perform, from carrying oxygen to fighting viruses to reading your DNA. Each one is a chain of amino acids, picked from just 20 options, represented as letters.

Music has 12 notes in an octave
Life has A S W K E 20 amino acids

If we mapped each amino acid to a note, what would it sound like?

Play famous proteins like hemoglobin. Hear how two proteins harmonize when they bind. Or compose your own sequence and watch it fold into a 3D shape.

Note assignments are an artistic choice; no physical law links amino acids to musical pitches.
