Lead thiolate containing precursor gels were prepared using conventional sol-gel processing techniques (Brinker and Scherer, 1990).
The gel was dried at 125[degrees]C for 30 min affording a dry, pale yellow lead thiolate doped silica gel precursor.
In this study, the accelerator thiolate fragment is considered directly coordinated to the zinc ion, not through a `poly-sulfur' or `poly-sulfur-thiolate' chain.
Hence, accelerator thiolate complexes having lower electron density in the S-Zn bond, higher electron density in the C-N bond and a weaker interaction between the ligand N and Zn, favor an increased rate of reaction.
were separated by vacuum filtration and washed several times by acetone, then they were purified by dissolution in hot chloroform (50[degrees]C) and reprecipitated by ethanol addition.
anion is an intermediate in the formation of album in-S-S-homocysteine.
Data show that the sulfhydryl thiolate
state is a significantly softer ([sigma]) nucleophile than either the corresponding thiol state or the other amino acid residues such as histidine or lysine.
1990), their ability to bind heavy metals, as with the MT1A isoform, depends on several factors: MT abundance in target tissues, mercury form in target tissues, and redox chemistry of MT and thiolate
(Maret and Vallee 1998).
Gut microbes were found to thiolate
and methvlate arsenic in both human and mouse models (Pinyayev et al.
2]-mediated inactivation of protein thiols is found in redox regulation of protein tyrosine phosphatases, in which the cysteine thiolate
in the catalytic center of the enzyme is reversibly oxidized by [H.
CYTOCHROME P-450 SUPERFAMILY OF HEME THIOLATE
Forty-four of those electrons were immobilized in bonds between gold atoms and thiolates
, leaving 58 electrons to fill a shell around the "superatom.
