3-Dehydroquinic Acid
3-Dehydroquinic acid (DHQ) is the first carbocyclic intermediate of the shikimate pathway. It is created from 3-deoxyarabinoheptulosonate 7-phosphate, a 7-carbon ulonic acid, by the enzyme DHQ synthase. The mechanism of ring closure is complex, but involves an aldol condensation at C-2 and C-7. It has the same structure as quinic acid, which is found in coffee, but the C-3 hydroxyl is oxidized to a ketone group. 3-Dehydroquinic acid undergoes five further enzymatic steps in the remainder of the shikimate pathway to chorismic acid, a precursor to tyrosine, 3-phenylalanine, tryptophan, and some vitamins, including: * Vitamin K * Pteroylmonoglutamic acid, called folate. 3-Dehydroquinate can also be a precursor to pyrroloquinoline quinone (PQQ), an alternate redox coenzyme involved in oxidative phosphorylation. Biosynthesis 3-Dehydroquinate goes through beta oxidation, similar to fatty acids. Then, this compound (6-oxo-3-dehydro-quinate) is transaminated to 6-amino-3-dehydroquin ...

Digital Humanities Quarterly
''Digital Humanities Quarterly'' is a peer-reviewed open-access academic journal covering all aspects of digital media in the humanities. The journal is also a community experiment in journal publication. The journal is funded and published by the Alliance of Digital Humanities Organizations and its editor-in-chief is Julia Flanders. Editorial policy ''Digital Humanities Quarterly'' has been noted among the "few interesting attempts to peer review born-digital scholarship."
