Examination of the Potential for Adaptive Chirality of the Nitrogen Chiral Center in Aza-Aspartame

Molecules, 2013
The potential for dynamic chirality of an azapeptide nitrogen was examined by substitution of nitrogen for the α-carbon of the aspartate residue in the sweetener S,S-aspartame.

Consistent treatment of hydrophobicity in protein lattice models accounts for cold denaturation

, 2015
The hydrophobic effect stabilizes the native structure of proteins by minimizing the unfavourable interactions between hydrophobic residues and water through the formation of a hydrophobic core. Here we include the entropic and enthalpic contributions of

Reactivity of Acyclic (pentadienyl)iron(1+) Cations with Phosphonate Stabilized Nucleophiles: Application to the Synthesis of Oxygenated Metabolites of Carvone [PDF]

, 2016
The addition of phosphonate stabilized carbon nucleophiles to acyclic (pentadienyl)iron(1+) cations proceeds predominantly at an internal carbon to afford (pentenediyl)iron complexes.

Vertical migration of some herbicides through undisturbed and homogenized soil columns

Orbital: The Electronic Journal of Chemistry, 2008
A laboratory experiment was conducted by using three herbicides, two from dinitroaniline group and one from thiocarbamate group to know their degree of downward movement (leachability) through soil columns and their contribution in ground water ...

Reducing Transfer of Salmonella and Aerobic Mesophilic Bacteria on Melon Rinds Surfaces to Fresh Juice by Washing With Chlorine: Effect of Waiting Period Before Refrigeration of Prepared Juice

Frontiers in Sustainable Food Systems, 2018
Cantaloupes, honeydew melons and watermelons inoculated with Salmonella cocktail at 4.5, 3.8, and 3.2 log10 CFU/cm2, respectively, were sanitized with 200 ppm chlorine before rinds removal, cutting, and juice preparation.

Calibrated Langevin dynamics simulations of intrinsically disordered proteins

, 2014
We perform extensive coarse-grained (CG) Langevin dynamics simulations of intrinsically disordered proteins (IDPs), which possess fluctuating conformational statistics between that for excluded volume random walks and collapsed globules.

Determination of the total phenolics in juices and superfruits by a novel chemical method

Journal of Functional Foods, 2011
The total phenols in foods and beverages are currently measured with Folin–Ciocalteu, through its reducing capacity. A novel method was developed to quantify polyphenols or phenolic compounds through direct interactions of polyphenols with Fast Blue BB ...

Developing an Acidic Residue Reactive and Sulfoxide-Containing MS-Cleavable Homobifunctional Cross-Linker for Probing Protein–Protein Interactions

Analytical Chemistry, 2016
Cross-linking mass spectrometry (XL-MS) has become a powerful strategy for defining protein–protein interactions and elucidating architectures of large protein complexes.

Homochirality in an early peptide world

, 2006
A recently proposed model of non-autocatalytic reactions in dipeptide reactions leading to spontaneous symmetry breaking and homochirality is examined. The model is governed by activation, polymerization, epimerization and depolymerization of amino acids.
