Measured impact first, then profile share

Every ingredient known to contain nonanone. Ingredients with a measured concentration come first, ranked by odour activity; the rest follow by how large a share of that ingredient's profile this molecule is. The figure beside each is how many different compounds that ingredient has in total — not the concentration of nonanone in it.
