Odorants & Odorless Compounds

Odorants are volatile and largely hydrophobic organic compounds possessing odors while odorless compounds are chemicals which do not possess or are associated with any odor. OlfactionBase comprises of 3985 odorant molecules representing an array of odors and 1124 odorless compounds. Odorant molecules are classified by 30 functional groups such as (acid, alcohol, aldehyde, alkane, cyclic, ether, ester, ketone, thiol, etc.). Each molecule entry includes detail information about physicochemical properties, odor profile, pharmacokinetic profile and drug likeness and cross-references to other biological databases. Among 3985 odorant molecules, 197 molecules are associated with 156 Olfactory receptors belonging to two species (Human and Mus musculus). The user-friendly interface of Olfactionbase facilitates exploration of chemicals in various ways: search chemical compounds with CAS No., odor and sub-odors, functional group, SMILES notation and molecular weight.
