Common Nametrans-Isohumulone
Descriptiontrans-Isohumulone is a member of the chemical class of iso-alpha acids, which are derived from the hops plant (Humulus lupulus) and are known for their role in brewing. Its chemical structure features a unique arrangement of isoprenoid chains and functional groups that contribute to its reactivity and biological activity. In biochemical pathways, trans-Isohumulone is involved in various transformations, such as the formation of carboxylic acids and proline amides when incubated with l-proline (PMID:25026227 ). It participates in oxidative reactions, leading to the production of hydroperoxy- and hydroxyl-allo-iso-alpha-acids, which have been characterized using advanced NMR and chromatography techniques (PMID:17624889 ). Additionally, trans-Isohumulone has been shown to induce the production of fructan and fructose-oligosaccharides in certain bacterial strains, enhancing transcription of genes related to these pathways under specific conditions (PMID:16464690 ). Its antibacterial properties are notable, exhibiting significantly greater activity compared to related compounds, which is influenced by the presence of monovalent cations (PMID:1517174 ). Furthermore, trans-Isohumulone undergoes photochemical transformations, leading to new derivatives, thereby highlighting its complex chemistry and potential applications (PMID:32027492 ).
