How this molecule is described

Sources disagree about odour more often than they disagree about chemistry. Rather than show one answer, here is every description on file with how many ingredient records carry it.

Descriptions on file

Ordered by how many independent descriptor streams give each wording, then by how often it appears. The bar is still replication — one source copied onto many ingredients scores high there — so the two can disagree.

Bars are the share of ingredient records carrying each description. High agreement means the sources replicate each other — not necessarily that they are right.

Where you'd actually smell it

Odor Activity Value = measured concentration ÷ odor threshold (1361763.56 ppb). OAV ≥ 1 = perceptible.

Measured impact first, then profile share

Every ingredient known to contain 3-hydroxyhexanoate. 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 3-hydroxyhexanoate in it. Full concentrations are in the OAV table above.
