Occurrence, Fate and Transport of the Primary Metabolites of Trenbolone Acetate in CAFO Soils and Surface Water Runoff
Metabolites of synthetic growth promoters used in industrial cattle production pose a demonstrated ecological risk to waterways adjacent to beef feedlot operations. For example, numerous studies have linked reproductive abnormalities in fish species to the presence of 17-α trenbolone and 17-β …

In vivo 13C stable isotope tracing of single leaf development in the cold
… versa. Hence, measuring the carbon allocation of metabolites enables a better understanding of the metabolic phenotype. The main challenge of such measurements is the in vivo integration of a stable or radioactive label into a plant without perturbation of the system. To follow the carbon flow of …

Investigating the physiological and metabolomic effects of Ecklonia maxima-derived biostimulant foliar application in ameliorating the effects of heat shock in tomato plants
… and proline assays. In addition, changes in the primary metabolites of the treated tomatoes were measured using gas chromatography mass spectrometry (GC-MS) to further elucidate the metabolic pathways involved in the responses to the different treatments. From the findings, it was shown that a …

A Phytochemical Analysis of Secondary Metabolites in Eupatorium Serotinum
… and unique properties of natural compounds. All metabolites are produced from the metabolic cycle, which is a pathway that provides energy for the organism. These metabolic compounds vary greatly and are classified based on their function within the organism. Primary metabolites are abundant and …

A robust pathfinding algorithm using chemical composition
… insensible shortcuts through pool or currency metabolites. In the past, strategies to circumvent such irrelevant pathways have included weighing networks using the degree of nodes or the manual curation of edges in the metabolic network. The former method wrongfully penalizes some primary …

Effects of systemic fungicides on floral attributes, pollination and fruit aroma in strawberries
… Moreover, fungicides may impact taste-relevant metabolites, thus impacting the fruit quality. However, there is a lack of studies which investigate these fungicide impacts, as existing studies often focus on individual impacts instead of considering the interrelationships between all associated …

Unindo fisiologia, bioquímica e metabolômica para desvendar respostas aos estresses abióticos da Glycine max e Ricinus communis.
… evaluated, as well as to identify and quantify primary metabolites in the seeds. Seed germination and establishment of soybean seedlings will also be evaluated at high temperature, followed by metabolomics analysis. As one of the main results, it is expected to relate the metabolomic analyzes …

Effects of Nutrients and Minerals on Growth and Detoxification in Phytophagous Insects
The availability of plant primary metabolites such as proteins, sugars, vitamins, and minerals can affect the ability of phytophagous insects to utilize a hostplant. One way dietary deficiencies of these compounds may reduce insect performance is by affecting activities of detoxification enzymes, …

Plasticity of Primary Metabolism in Parasitic Orobanchaceae
… were addressed using comparative profiling of primary metabolites to gain insight into carbon and nitrogen assimilation by the obligate holoparasite Phelipanche aegyptiaca and the facultative hemiparasite Triphysaria versicolor. First, metabolite profiles of these parasites and their hosts were …

The Development and Application of Non- Targeted Mass Spectrometry Based Methods to Tea (Camellia Sinensis L.)
… to measure changes in the abundance of as many metabolites as possible (both known and unknown) in a single sample. Methodologies to perform this demanding task require regular improvement to keep pace with on-going technological advances in chromatography and mass spectrometry. Thus a major …

Development of integrated imaging techniques for investigating biomarkers in glioblastoma
… on GBM. By evaluating changes in the levels of metabolites predominant in GBM during the treatment, we observed an antitumor response in GBM after one month. Notably, the index of the ratio of primary metabolites, NAA/Cho, in tumor strongly predicted 6-month overall survival; these data …

A Metabolomics-Based Analysis of Acyl-Homoserine Lactone Quorum Sensing in Pseudomonas aeruginosa
… the relationship between QS and small molecule primary metabolism, using metabolomic methods based on nuclear magnetic resonance spectroscopy and mass spectrometry. Analysis of extracellular metabolic profiles (the bacteria’s “metabolic footprint”) established that QS can modulate the uptake and …

Investigations into the molecular basis of enzyme-catalyzed reactions in natural product biosynthesis
… that can be grouped into two broad categories. Primary metabolites are involved in central metabolism and are essential for the survival of the organism. On the other hand, secondary metabolites are produced by organisms for an ‘added advantage’ effect. These molecules may be responsible for …

Metabolomic profiles of Oryza sativa and influence of genetic diversity
… Genes in biochemical pathways for health-related metabolites were interrogated for allelic variation by single nucleotide polymorphisms (SNPs). SNP variation may serve as an important mechanism by which genes influence metabolic variation. The influence of genetic diversity on the metabolite …
