Melanin has a lot of similarities with proteins, and, while not technically a protein, itself, it is made by proteins. Different versions of the proteins that make melanin can make different forms of the pigment. Natural human hair is colored by 2 forms of melanin: pheomelanin and eumelanin. Use the model to see which types of melanin are in which hair colors (and how much of each is there).

To check the melanin levels in each hair color, choose a hair color, click “Setup” then “check-protein-quantities” and record the data.
