Methanol and isoprene emissions from the fast growing tropical pioneer species Vismia guianensis (Aubl.) Pers. (Hypericaceae) in the central Amazon forest [PDF]

Atmospheric Chemistry and Physics, 2016
Isoprene (Is) emissions by plants represent a loss of carbon and energy resources leading to the initial hypothesis that fast growing pioneer species in secondary tropical forests allocate carbon primarily to growth at the expense of isoprenoid ...

Evolutionary, Functional and Mechanistic Characterisation of Microbial Terpene Synthase‐Like Genes From Springtails

Angewandte Chemie International Edition, EarlyView.
A genome analysis revealed the presence of many bacterial‐type terpene synthases in springtails. Four enzymes from Sinella curviseta were functionally characterised, resulting in the isolation of several compounds including sinellene ether, the first diterpene ether identified from a terpene synthase that represents a novel skeleton.

Metabolism and mutagenicity of isoprene.

Environmental Health Perspectives, 1990
Liver microsomes of various rodents (mouse, rat, rabbit, and hamster) metabolize isoprene (2-methyl-1,3-butadiene) to the corresponding monoepoxides 3,4-epoxy-3-methyl-1-butene and 3,4-epoxy-2-methyl-1-butene. 3,4-Epoxy-3-methyl-1-butene (half-life 85 min) was found to be the main metabolite, although the stable 3,4-epoxy-2-methyl-1-butene was also ...

Seasonal Fluctuations of Plastochromanol‐8 and α‐Tocopherol Amounts in the Leaves of Cecropia Trees

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Plastochromanol‐8 (PC‐8) is a homologue of γ‐tocotrienol with a longer side chain (eight instead of three isoprene units) and therefore also a representative of the tocochromanol (vitamin E) group. PC‐8 has been determined in various plants and seeds, with Cecropia sp. leaves showing unusually high levels.

Isoprene emission characteristics of tall and dwarf bamboos

Atmospheric Environment: X, 2021
Considerable isoprene emissions from several bamboo species have been reported. However, bamboos are highly diverse in taxonomy and have different niches or habitats among species, and the present investigation might be insufficient to conclude a ...

Comprehensive Characterization of Acer truncatum Leaf Extract: Identification of Systemic Metabolites and Effects on Performance, Antioxidant Status, and Intestinal Microbiota in Laying Hens

Animal Research and One Health, EarlyView.
Dietary A. truncatum leaf extract is absorbed and improves laying performance in aged hens by enhancing systemic antioxidant capacity and modulating the gut microbiota. ABSTRACT The demand for natural feed additives is considerably increasing in the antibiotic‐free feed era.

Synergetic Effects of Isoprene and HOx on Biogenic New Particle Formation

Geophysical Research Letters, 2023
New particle formation (NPF) has been observed at various locations, but NPF does not occur in isoprene‐dominant forests. Recent laboratory studies were conducted to understand the role of isoprene in biogenic NPF, and these studies show that isoprene ...

Edge Growth Form of European Buckthorn Increases Isoprene Emissions From Urban Forests

Frontiers in Forests and Global Change, 2021
Urban trees provide numerous benefits, such as cooling from transpiration, carbon sequestration, and street aesthetics. But volatile organic compound emissions from trees can combine with anthropogenic nitrogen oxide emissions to form ozone, a harmful ...

Rewiring nutrition: Chemical insights into the physiological and microbiological roles of food's microconstituents

Food Biomacromolecules, EarlyView.
Bidirectional interactions between food‐derived sensory compounds, gut sensing and microbiota, host physiological feedback, and metabolite production within the food matrix collectively shape sensory perception, microbial dynamics, and metabolic health.
