Electric Literature of 24034-73-9, In chemistry, an alcohol is a type of organic compound that carries at least one hydroxyl functional group (−OH) bound to a saturated carbon atom. 24034-73-9, name is (2E,6E,10E)-3,7,11,15-Tetramethylhexadeca-2,6,10,14-tetraen-1-ol, An important class of alcohols, of which methanol and ethanol are the simplest examples, includes all compounds which conform to the general formula CnH2n+1OH.
Kruk, Jerzy;Gabruk, Michal;Kryszczak, Marian;Wasik, Piotr research published 《 Protochlorophylls in Cucurbitaceae – Distribution, biosynthesis and phylogeny》, the research content is summarized as follows. Using high-resolution chromatog. we resolved monovinyl (MV)- and divinyl (DV)-protochlorophylls (Pchls) and detected all of their side-chain homologues in the inner seed coat of Cucurbita maxima, C. pepo and their varieties. Furthermore, we analyzed other less common representatives of the Cucurbitaceae family that were found to accumulate mostly MV-Pchls. All these species and varieties showed the characteristic composition of individual Pchls. Addnl., we also detected all of the corresponding protopheophytins, which accounted for between 1.1 and 35.5% of Pchls and are supposed to be degradation products of Pchls, formed during seed storage. A pigment composition anal. of C. maxima seedlings performed during deetiolation revealed that chlorophyll (Chl) a content increased gradually, while the levels of Pchl-GG and Chl-GG, a precursor of Chl a, were low and did not change significantly. However, when the seedlings were incubated with the precursor of tetrapyrrole biosynthesis (δ-aminolevulinic acid) before illumination, the Chl-GG content increased dramatically, while synthesis of Chl a was inhibited. These data indicate that in C. maxima seedlings, Chl a is not synthesized from geranylgeranyl-pyrophoshate via Chl-GG, but rather directly from phytyl-pyrophosphate. Phylogenetic anal. of Chl synthase genes revealed that many species, including those of the Cucurbitaceae family, have two or more Chl synthase genes. This suggests that these addnl. genes, at least in some species, might encode isoforms involved in Pchl synthesis.
Electric Literature 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.
