Peptides are short strings of amino acids. Like a line of code, the order of the letters is the instruction. When a peptide fits a receptor on a cell, the cell runs the program: repair, calm, focus, defend.

How the code works

1. The code: a peptide’s amino-acid sequence is the message.
2. The port: it only runs where it fits the right receptor, the way a prompt only works in the right app.
3. The output: once it docks, the cell carries out the instruction.
