[NMR paper] Compositional and optical characteristics of aqueous brown carbon and HULIS in the eastern Indo-Gangetic Plain using a coupled EEM PARAFAC, FT-IR and (1)H NMR approach
Compositional and optical characteristics of aqueous brown carbon and HULIS in the eastern Indo-Gangetic Plain using a coupled EEM PARAFAC, FT-IR and (1)H NMR approach
This study provides insights into the fluorophoric composition of aqueous brown carbon (BrC(aq)) and chemically-separated humic-like substances (HULIS): neutral HULIS (HULIS-n; at pH = 7) and acidic HULIS (HULIS-a; at pH = 2) on a seasonal and day-night basis in the eastern Indo-Gangetic Plain (IGP), India. A coupled approach including excitation-emission matrix (EEM) fluorescence and parallel factor analysis (PARAFAC) model, Fourier-transformed infrared spectroscopy (FT-IR) and proton nuclear...
[NMR paper] Unraveling Compositional Study, Chemometric Analysis, and Cell-Based Antioxidant Potential of Selective High Nutraceutical Value Amaranth Cultivars Using a GC-MS and NMR-Based Metabolomics Approach
Unraveling Compositional Study, Chemometric Analysis, and Cell-Based Antioxidant Potential of Selective High Nutraceutical Value Amaranth Cultivars Using a GC-MS and NMR-Based Metabolomics Approach
Amaranthus (family Amaranthaceae) is a potentially nutritious pseudocereal also known as a functional food owing to its high nutritional quality grains especially rich in essential amino acids. Emerging study, however, unambiguously indicates that apart from essential nutrients like protein, other phytochemicals present in amaranth seeds provide excellent health benefits. Squalene is one such...

[NMR paper] Insights into the binding of Ag ions with SilE model peptides: an NMR and MS coupled approach
Insights into the binding of Ag ions with SilE model peptides: an NMR and MS coupled approach
The diffuse and renewed use of silver as antimicrobial agent has caused the development of resistance to silver ions in some bacterial strains, posing a serious threat for health systems. In order to cast light on the mechanistic features of resistance, here, we aimed to understand how silver interacts with the periplasmic metal-binding protein SilE which is engaged in bacterial silver detoxification. This aim was addressed by studying two peptide portions of SilE sequence (SP2 and SP3) that...

Abstract
Low-molecular-weight metabolites in human milk are gaining increasing interest in studies of infant nutrition. In the present study, the milk metabolome...
[NMR analysis blog] Hexacyclinol - NMR spectra vs plain images
Hexacyclinol - NMR spectra vs plain images
I’m sure that many of you are aware of the infamous controversy over the total synthesis of Hexacyclinol . There are a plethora of arguments, from the purely synthetic chemical point of view to the spectroscopist perspective, which both put in doubt the veracity of aforementioned total synthesis. You can find, at the end of this post, a list of references that may be of interest on this subject. In this particular post, I would like to comment on several interesting aspects from an NMR standpoint.
In the original article’s “supporting...
