Metabolomic profile and discrimination of white quinoa seeds from Peru based on UHPLC-HRMS and multivariate analysis
(Elsevier, 2021)
In the present work, an untargeted metabolomic approach based on ultra-high-performance liquid chromatography coupled with high-resolution mass spectrometry (UHPLC–HRMS) was performed for the discrimination of 25 accessions ...
Metabolomic profile and discrimination of white quinoa seeds from Peru based on UHPLC-HRMS and multivariate analysis
(International Association for Cereal Science and Technology-, 2021-09)
In the present work, an untargeted metabolomic approach based on ultra-high-performance liquid chromatography coupled with high-resolution mass spectrometry (UHPLC–HRMS) was performed for the discrimination of 25 accessions ...
Metabolomics as a tool for the comprehensive understanding of fermented and functional foods with lactic acid bacteria
(Elsevier Science, 2013-11)
Metabolomics, also called metabonomics or metabolic profiling, deals with the simultaneous determination and quantitative analysis of intracellular metabolites or low-molecular-mass molecules. The metabolomics field, ...
In Situ Metabolomics of the Honeybee Brain: The Metabolism of l -Arginine through the Polyamine Pathway in the Proboscis Extension Response (PER)
(2020-02-07)
The proboscis extension response (PER) reflex may be used to condition the pairing of an odor with sucrose, which is applied to the antennae, in experiments to induce learning, where the odor represents a conditioned ...
Exploratory analysis using MRM profiling mass spectrometry of a candidate metabolomics sample for testing system suitability
(2021-10-01)
Multiple reaction monitoring (MRM) profiling is an exploratory mass spectrometry (MS) method applicable to the initial screening of complex samples for small molecules based on their chemical functionalities. We report on ...
Outdoor versus indoor cultivation: Effects on the metabolite profile of Agaricus subrufescens strains analyzed by untargeted metabolomics
(2022-04-16)
Agaricus subrufescens has emerged as an important culinary-medicinal mushroom over the last decades. Efforts have been dedicated to upgrade the A. subrufescens productive process via strain selection and cultivation ...
Proteomic and metabolomic characterization of COVID-19 patient sera
Early detection and effective treatment of severe COVID-19 patients remain major challenges. Here, we performed proteomic and metabolomic profiling of sera from 46 COVID-19 and 53 control individuals. We then
trained a ...
Metabolomic characterization of 5 native Peruvian chili peppers (Capsicum spp.) as a tool for species discrimination
(Elsevier, 2022)
Many species of chili peppers have overlapping morphological characters and delimitation by visual descriptors in many cases fails to differentiate one species from another. In Peru, there are 413 accessions of native chili ...
Plant Metabolomics Using NMR Spectroscopy
(2019-01-01)
The major goal in plant metabolomics is to study complex extracts for the purposes of metabolic exploration and natural products discovery. To achieve this goal, plant metabolomics relies on accurate and selective acquisition ...
