Descriptors for terpene esters from chromatographic and partition measurements: Estimation of human odor detection thresholds [PDF]

open access: yes, 2020
We have used gas chromatographic retention data together with other data to obtain Abraham descriptors for 30 terpene esters. These include the air-water partition coefficient, as log Kw, for which no experimental values are available for any terpene ...

Epoxidation of Terpenes [PDF]

open access: yesCatalysts, 2021
Terpene epoxides are considered as potential primary intermediates in the synthesis of numerous green polymers including epoxy resins, polycarbonates, nonisocyanate polyurethanes and even some polyamides. In this chapter we describe recent efforts from our group to develop catalytic and noncatalytic processes for terpene epoxidation using a variety of ...

Terpene Synthases as Metabolic Gatekeepers in the Evolution of Plant Terpenoid Chemical Diversity

open access: yesFrontiers in Plant Science, 2019
Terpenoids comprise tens of thousands of small molecule natural products that are widely distributed across all domains of life. Plants produce by far the largest array of terpenoids with various roles in development and chemical ecology.

The TriForC database : a comprehensive up-to-date resource of plant triterpene biosynthesis [PDF]

open access: yes, 2018
Triterpenes constitute a large and important class of plant natural products with diverse structures and functions. Their biological roles range from membrane structural components over plant hormones to specialized plant defence compounds.

Further Biochemical Profiling of Hypholoma fasciculare Metabolome Reveals Its Chemogenetic Diversity

open access: yesFrontiers in Bioengineering and Biotechnology, 2021
Natural products with novel chemistry are urgently needed to battle the continued increase in microbial drug resistance. Mushroom-forming fungi are underutilized as a source of novel antibiotics in the literature due to their challenging culture ...

Origins and composition of fine atmospheric carbonaceous aerosol in the Sierra Nevada Mountains, California [PDF]

open access: yes, 2011
In this paper we report chemically resolved measurements of organic aerosol (OA) and related tracers during the Biosphere Effects on Aerosols and Photochemistry Experiment (BEARPEX) at the Blodgett Forest Research Station, California from 15 August–10 ...

Oleoresin defenses in conifers: chemical diversity, terpene synthases, limitations of oleoresin defense under climate change.

open access: yesNew Phytologist, 2019
Conifers have evolved complex oleoresin terpene defenses against herbivores and pathogens. In co-evolved bark beetles, conifer terpenes also serve chemo-ecological functions as pheromone precursors, chemical barcodes for host identification, or nutrients

Terpene synthases in disguise: enzymology, structure, and opportunities of non-canonical terpene synthases.

open access: yesNatural product reports (Print), 2020
Covering: up to July 2019Terpene synthases (TSs) are responsible for generating much of the structural diversity found in the superfamily of terpenoid natural products. These elegant enzymes mediate complex carbocation-based cyclization and rearrangement

Transcriptome pathways unique to dehydration tolerant relatives of modern wheat [PDF]

open access: yes, 2009
Among abiotic stressors, drought is a major factor responsible for dramatic yield loss in agriculture. In order to reveal differences in global expression profiles of drought tolerant and sensitive wild emmer wheat genotypes, a previously deployed shock ...
