i·so·pren·oids

(ī'sō-prēn'oydz),
Polymers with whose carbon skeletons that consist in whole or in large part of isoprene units joined end to end, for example, carotene, lycopene, vitamin A. Vitamins K and E and the coenzyme Q have isoprenoid side chains.

The presence of isoprenoids (triterpenoid/steroids, cardenolides) and fatty acids as metabolites in the NHE from phytochemical screening using appropriate standard reagents corroborated our earlier report about the presence of these metabolites in a closely related species Pleurotus tuber regium" The observed dose-dependent plasmodium pLDH inhibition by the NHE from the fruiting bodies of P.
These included 2 fatty aldehydes; nonanal (16) and 2E-decenal (20); 2 fatty alcohols, lignocerol (68) and pentacosyl alcohol (73); four isoprenoids, phytane (36), iso-phytol (42), hexahydrofarnesyl acetone (43), and E-phytol (57), and 2 phytosterols, O-Sitosterol (79) and fucosterol (81).
Ferredoxin (Fd) and Fd-NADP+ reductase (FNR) in apicoplast constitute a redox system [11,12] that is homologous to those of plant chloroplast and algae, especially green and red algae [8, 13].The involvement of apicoplast Fd has been indicated in the reactions of an Fe-S cluster assembly [14] and isoprenoid biosynthesis pathways [10, 15], fatty acid desaturation [5], and heme oxygenation [16].
A pseudo homologous series of aryl isoprenoids were revealed from mass chromatograms of m/z 133 in the Upper Permian Dalong Fm and some Silurian source rocks (samples HYS-6, HYS-8, HYS-11, and TJ-7-104, but not from Guanba, Shiniulan, and ZB21, Figure 3 and Table 1).
DEINOCHEM first targets isoprenoids, which constitute one of the families of the most diverse natural substances (over 22,000 isoprenoid compounds are listed to date).
Isoprenoids are highly reactive and as a consequence significantly affect the chemical and physical properties of the atmosphere (Chameides et al., 1988; Centritto et al., 2011); through the formation of tropospheric O3 and secondary organic aerosols, in addition to influencing the lifetime of powerful greenhouse gases including methane (Trainer et al., 1987; Fuentes et al., 2000; Claeys et al., 2004).
(8,9) Terpenoids, or isoprenoids, are a subclass of prenyllipids, which include prenylquinones, sterols, and terpenes, the largest class of natural substances.

They reported that statins caused the "abrogation of insulin action." HMG-CoA (3-hydroxy-3-methylglutaryl-Coenzyme A) reductase inhibitors disrupt cellular processes by the depletion of isoprenoids and dolichols that are intimately involved with insulin and insulin-like growth factor (IGF) signaling, including receptor functions.
In addition, MVA pathway synthesizes mevalonic acid and isoprenoids (Miziorko, 2011).
The MP has been reported as a metabolic sequence modulated by isoprenoids (Mo and Elson 2004; Ong et al.
