Hazard Information | Back Directory | [Uses]
Isohumulone is a chemical compound that contributes to the bitter taste of beer. It belongs to a class of compound known as the Iso-alpha acids found in the hops. | [Definition]
ChEBI: A cyclic ketone that is the naturally occurring (4S,5R) enantiomer of the cis-isomer of isohumolone, produced during the brewing process due to thermal isomerism, which converts humulones to isohumulones v
a an acyloin-type ring contraction. |
