Abstract

Over the past decade, metabolomics has developed into a major tool for studying the metabolism of organisms and cells, and through this approach much has been learned about metabolic networks and the reactions of organisms to various external conditions (Lay et al., 2006). Most of this work involves a number of chemometric methods to identify markers in the metabolomic data for various events. But in fact, little work has been done on understanding the meaning of the metabolomic data itself and the role of the total of the compounds observed. Is there any logic in the studying the combination of compounds itself, instead of looking at the correlations between the compounds observed and any disease or applied experimental conditions? NMR-based metabolomics in particular give a clear view of the major compounds present in an organism or cell and enable the direct quantitative comparison of all major compounds. Considering all the information we have collected in recent years using our protocol for NMR-based metabolomics (Kim et al., 2010), we asked ourselves why a few very simple molecules are always present in considerable amounts in all microbial, mammalian, and plant cells. It seems that these compounds must serve some basic function in living cells and organisms. These compounds include sugars, some amino acids, choline, and some organic acids such as malic acid, citric acid, lactic acid, and succinic acid. With the exception of sugars, which may serve as storage products and a source of energy, the other compounds are present in such large amounts that it does not make sense to consider them as only intermediates in metabolic pathways.

  • NADES were suggested as solvents for protein and DNA stabilization.

    “Furthermore, NADES were also suggested as solvents for protein (e.g.lysozyme, amylase, photosynthetic enzymes) and DNA stabilization (Choi et al. 2011;Dai et al. 2014;Milano et al. 2017;Xin et al. 2017).”

    From The perspectives of natural deep eutectic solvents in agri-food sector (2020) · cites this paper as Choi et al. 2011

    In the paper’s discussion of drought and germination (page unavailable), the authors suggest that proteins could be conserved in NADES and enzymes could remain stable. The solubility discussion reports that salmon DNA dissolves in a tested NADES, but does not suggest that NADES stabilizes DNA. Thus, Choi et al. support the protein-stabilization part, not the DNA-stabilization part. (LLM, conf=0.86)

  • Physicochemical properties of NADES (viscosity, conductivity, density, and polarity) affect their end-use.

    “The physicochemical properties of the NADES (viscosity, conductivity, density and polarity) affect their end-use (Choi et al. 2011;Dai et al. 2013b).”

    From The perspectives of natural deep eutectic solvents in agri-food sector (2020) · cites this paper as Choi et al. 2011

    In the paper’s main text (page not provided), Choi et al. describe NADES as viscous liquids and show that different NADES dissolve compounds to different degrees. They also propose uses as extraction and reaction solvents. Our copy does not establish that conductivity, density, or polarity affect end-use, so the full list of properties is not supported. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • NADES were first described by Choi et al. (2011) as a third class of liquids present in living cells, different from water and lipids, that serve as an alternative medium for biosynthesis, transport, and storage of compounds with intermediate polarity.

    “Natural deep eutectic solvents (NADES) are firstly described by Choi et al. (2011) as a third class of liquids present in living cells, different from water and lipids, that play an important role as an alternative medium for biosynthesis, transport and storage of compounds with intermediate polarity.”

  • NADESs are even more environmentally friendly than DESs due to their natural origin.

    “Besides all the advantages of DESs, NADESs are even more environmentally friendly due to their natural origin [13].”

    From Application of deep eutectic solvents in analytical chemistry. A review (2017) · cites this paper as [13]

    The paper’s concluding discussion (page not specified in our copy) describes NADES as natural, nontoxic, sustainable, and environmentally friendly. It presents them as alternatives to toxic synthetic ionic liquids, but does not say they are more environmentally friendly than DESs or establish that comparison on the basis of natural origin. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Natural deep eutectic solvents (NADESs) were introduced into analytical practice as an alternative type of extraction solvent.

    “Recently, natural deep eutectic solvents (NADESs) were introduced into analytical practice as an alternative type of extraction solvent.”

    From Application of deep eutectic solvents in analytical chemistry. A review (2017) · cites this paper as [13]

    The paper introduces NADES and identifies extraction as a potential use. It does not say they had been introduced into analytical practice as extraction solvents; it presents that application as a possibility, not an established practice. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
