ENDOR studies of VO2+: probing protein-metal ion …

Spectra of the VO2+-complex of EMA showed axial water loed trans to the V=O bond and outer shell water hydrogen-bonded to the vanadyl oxygen, consistent with the X-ray structure of Ca(EMA)2. We, therefore, conclude that the spatial disposition of carboxylate groups of Gla residues coordinating Ca2+ in isoforms A and B must differ from that observed in the crystal structure of Ca(EMA)2.

Covalent Bond - an overview | ScienceDirect Topics

In a single covalent bond, when the electrons are shared between two s orbitals, the resulting bond is a sigma (σ) bond as shown in Figure 3-4.Sigma bonds are the strongest covalent chemical bonds. Sigma bonds also occur when an s and a p orbital share a pair of electrons or when two p orbitals that are parallel to the internuclear axis share a pair of electrons (see Figure 3-4).

SODIUM METAL IS a strong reducing agent, will reduce alkynes to trans-alkenes. Will also form hydrogen gas when added to alcohols, resulting in alkoxides. Will also reduce aromatic groups to alkenes (the Birch reduction). Sodium metal will generally not reduce

What causes ions to form ionic bonds? - A Plus Topper

The non-metal atoms accept the electrons donated by the metal atoms to achieve a stable noble gas electron arrangement. Thus, negatively-charged ions are formed. The positively-charged ions and negatively-charged ions are then attracted to each other by strong electrostatic forces which are closely-packed in an orderly manner in a crystal lattice, forming an ionic compound.

Calcium Carbonate - an overview | ScienceDirect Topics

Commercial calcium carbonate products typically contain at least 95–98% CC, with the remainder being various metal oxides. CC for plastics may be ground from limestone (such as dolomite) or another natural raw source, or chemically precipitated into fine, uniform particles with predictable properties.

Oxidative Post-translational Modifiions Accelerate …

Remarkably, disulfide bond formation accelerates proteolytic degradation of CP. We propose a new extension to the working model for extracellular CP where post-translational oxidation by reactive oxygen species generated during the neutrophil oxidative burst modulates its lifetime in the extracellular space.

The mechanism of action of vitamin K - PubMed

The model comprises an oxygenation that is coupled to carbon-carbon bond formation, as is the oxygenation of vitamin K hydroquinone to vitamin K oxide. The model hypothesis is also supported by the mechanism of inhibition of the carboxylase by HCN, which acts as an acid-base inhibitor rather than a metal-complexing inhibitor.
