It is detected and released by orchid flowers, e.g. Dendrobium superbum (syn D. anosmum), [4] and several Bulbophyllum species [5] [6] [7] to attract raspberry ketone-responsive male Dacini fruit flies. It is biosynthesized from coumaroyl-CoA. [8] It can be extracted from the fruit, yielding about 1–4 mg per kg of raspberries. [9]
Butanone, also known as methyl ethyl ketone (MEK) or ethyl methyl ketone, [a] is an organic compound with the formula CH 3 C(O)CH 2 CH 3. This colorless liquid ketone has a sharp, sweet odor reminiscent of acetone .
4-Hydroxyphenylglycine (HPG) is a non-proteogenic amino acid found in vancomycin and related glycopeptides. HPG is synthesized from the shikimic acid pathway and requires four enzymes to synthesize: [ 1 ] Both L - and D -HPG are used in the vancomycin class of antibiotics.
The enzyme 3,4-dihydroxy-2-butanone 4-phosphate synthase (DHBP synthase) (RibB) EC 4.1.99.12 catalyses the conversion of D-ribulose 5-phosphate to formate and 3,4-dihydroxy-2-butanone 4-phosphate, the latter serving as the biosynthetic precursor for the xylene ring of riboflavin. [1]
3,4-Methylenedioxyphenylpropan-2-one [1] or piperonyl methyl ketone (MDP2P or PMK) is a chemical compound consisting of a phenylacetone moiety substituted with a methylenedioxy functional group. It is commonly synthesized from either safrole (which, for comparison, is 3-[3,4-(methylenedioxy)phenyl]-2-propene) or its isomer isosafrole via ...
4-HO-TMT, or 4-OH-TMT, also known as 4-hydroxy-N,N,N-trimethyltryptammonium or as dephosphorylated aeruginascin, is a substituted tryptamine derivative and the active form of aeruginascin (4-PO-TMT), analogously to how psilocin (4-HO-DMT) is the active form of psilocybin (4-PO-DMT).
Benzylacetone (IUPAC name: 4-phenylbutan-2-one) is a liquid with a sweet, flowery smell that is considered to be the most abundant attractant compound in flowers (e.g. Coyote Tobacco, Nicotiana attenuata) [1] [2] and one of volatile components of cocoa.
[3] [4] In both species, it is subsequently metabolized into 4-hydroxyphenylacetate by aldehyde dehydrogenase (ALDH) enzymes in humans and the phenylacetaldehyde dehydrogenase (feaB) enzyme in E. coli. [3] [4] [5] The condensation of 4-hydroxyphenylacetaldehyde and dopamine is a key step in the biosynthesis of benzylisoquinoline alkaloids.
