Molecules

Thirty-two molecules, sorted by name, grouped by letter. The aroma molecules: identity from PubChem, where each occurs, the words used for its smell and the rules that apply.

Each line is one record page: the name, a short fact, and the first line of the record. Every field on the page carries its source. Choose a group to show only that group; “All” shows them all again.
