In general, the hydroxyl group makes alcohols polar. 24034-73-9, formula is C20H34O, Because of hydrogen bonding, alcohols tend to have higher boiling points than comparable hydrocarbons and ethers. Synthetic Route of 24034-73-9
Uno, Shinpei;Masuya, Takahiro;Shinzawa-Itoh, Kyoko;Lasham, Jonathan;Haapanen, Outi;Shiba, Tomoo;Inaoka, Daniel Ken;Sharma, Vivek;Murai, Masatoshi;Miyoshi, Hideto research published 《 Oversized ubiquinones as molecular probes for structural dynamics of the ubiquinone reaction site in mitochondrial respiratory complex I》, the research content is summarized as follows. NADH-quinone oxidoreductase (complex I) couples electron transfer from NADH to quinone with proton translocation across the membrane. Quinone reduction is a key step for energy transmission from the site of quinone reduction to the remotely located proton-pumping machinery of the enzyme. Although structural biol. studies have proposed the existence of a long and narrow quinone-access channel, the physiol. relevance of this channel remains debatable. We investigated here whether complex I in bovine heart submitochondrial particles (SMPs) can catalytically reduce a series of oversized ubiquinones (OS-UQs), which are highly unlikely to transit the narrow channel because their side chain includes a bulky “block” that is ∼13 Å across. We found that some OS-UQs function as efficient electron acceptors from complex I, accepting electrons with an efficiency comparable with ubiquinone-2. The catalytic reduction and proton translocation coupled with this reduction were completely inhibited by different quinone-site inhibitors, indicating that the reduction of OS-UQs takes place at the physiol. reaction site for ubiquinone. Notably, the proton-translocating efficiencies of OS-UQs significantly varied depending on their side-chain structures, suggesting that the reaction characteristics of OS-UQs affect the predicted structural changes of the quinone reaction site required for triggering proton translocation. These results are difficult to reconcile with the current channel model; rather, the access path for ubiquinone may be open to allow OS-UQs to access the reaction site. Nevertheless, contrary to the observations in SMPs, OSUQs were not catalytically reduced by isolated complex I reconstituted into liposomes. We discuss possible reasons for these contradictory results.
Synthetic Route of 24034-73-9, Geranylgeraniol is a diterpenoid that is hexadeca-2,6,10,14-tetraene substituted by methyl groups at positions 3, 7, 11 and 15 and a hydroxy group at position 1. It has a role as a plant metabolite, a volatile oil component and an antileishmanial agent. It is a diterpenoid and a polyprenol.
Geranylgeraniol, a precursor to geranylgeranylpyrophosphate, is an intermediate in the mevalonate pathway. Geranylgeraniol has been shown to prevent bone re-absorption, inhibition of osteoclast formation, and kinase activation in vitro. When working with statins, Geranylgeraniol can reduce the toxicity without inhibiting the cholesterol-producing effects. Geranylgeraniol has been documented to counteract the effects of fluvastatin by inhibiting activation of caspase-1 and production of IL-1. Additionally Geranylgeraniol has been found to induce apoptosis in HL-60 cells.
