Conversion of deoxyhumulone into the HOP α-acid humulone

In the final step of the biosynthesis of hop bitter acids an oxidation leads to the formation of α-acids. A method was set up to analyse the bitter acids in the presence of proteins, since proteins from a crude hop extract were found to interact with the

Hydroperoxy-desoxyhumulones

Humulones (I) are made by subjecting desoxyhumulones (II) to oxidation to form novel hydroperoxides (III) and reducing the latter. The humulones are used to make known isohumulones (IV) which are bitter substances useful in the beverage industry.
