Crystallization and preliminary X-ray analysis of neoagarobiose hydrolase from Saccharophagus degradans 2-40 [PDF]
, 2009 Many agarolytic bacteria degrade agar polysaccharide into the disaccharide unit neoagarobiose [O-3,6-anhydro-α-L-galactopyranosyl-(1→3)-D-galactose] using various β-agarases.

Weak Acids Enhance Halogen Activation on Atmospheric Water’s Surfaces [PDF]
, 2011 We report that rates of I_2(g) emissions, measured via cavity ring-down spectroscopy, during the heterogeneous ozonation of interfacial iodide: I^–(surface, s) + O_3(g) + H+(s) →→ I_2(g), are enhanced several-fold, whereas those of IO·(g) are unaffected,

Rock-eating mycorrhizas: their role in plant nutrition and biogeochemical cycles [PDF]
, 2014 A decade ago, tunnels inside mineral grains were found that were likely formed by hyphae of ectomycorrhizal (EcM) fungi. This observation implied that EcM fungi can dissolve mineral grains. The observation raised several questions on the ecology of these

Mass Spectra of 2-Substituted Diethyl Malonate Derivatives
Molecules, 1999 Addition of Grignard derivatives to diethyl ethoxymethylene malonate generates 2-substituted diethyl malonate derivatives. This paper reports the mass spectral data for these derivatives.

Gas phase carbon acidity and correlations with aqueous pK~a~ values: A comparison of B3LYP/6-311++G(d,p), Gaussian-4 (G4), and experimental approaches [PDF]
, 2010 Gas phase standard state (298.15 K, 1 atm) calculations were conducted at the B3LYP/6-311++G(d,p) density functional and the Gaussian-4 (G4) composite method levels of theory to estimate the acidity of various carbon acids.

Frontiers in Pharmacology, 2012 Ever since it was shown for the first time that lactate can support neuronal function in vitro as a sole oxidative energy substrate, investigators in the field of neuroenergetics have been debating the role, if any, of this glycolytic product in cerebral

Journal of Pharmacological Sciences, 2021 Hydroxyl radical (•OH) production in the rat striatum during carbon monoxide (CO) poisoning, which inhibits complex IV, was enhanced synergistically by malonate, a mitochondrial complex II inhibitor, but not N-methyl-4-phenylpyridinium or NaCN, complex I

Metabolites, 2019 Cerebral micro-dialysis allows continuous sampling of extracellular metabolites, including glucose, lactate and pyruvate. Transient ischemic events cause a rapid drop in glucose and a rise in lactate levels. Following such events, the lactate/pyruvate (L/

Electrochemical Perspective on Hematite–Malonate Interactions
Colloids and Interfaces, 2021 Organic matter (OM) interactions with minerals are essential in OM preservation against decomposition in the environment. Here, by combining potentiometric and electrophoretic measurements, we probed the mode of coordination and the role of pH-dependent ...

Taming tosyl azide: the development of a scalable continuous diazo transfer process [PDF]
, 2016 Heat and shock sensitive tosyl azide was generated and used on demand in a telescoped diazo transfer process. Small quantities of tosyl azide were accessed in a one pot batch procedure using shelf stable, readily available reagents. For large scale diazo
