But two silane coupling agents, tertrasulfide and disulfide
, were close, and even had a bigger loss angle than that of 3 when at very small deformation.
bonds, which covalently link two adjacent polypeptide chains, are very strong bonds formed within cystine, an amino acid found in keratin, the principal protein of hair.
4) to remove low-molecular weight thiols and disulfides
He notes that permed hair typically has only 90 percent of the original number of disulfide
bonds, leaving the hairdo weaker than before.
firm applies low-friction tungsten disulfide
dry-film lubricant coating to molds and ejector pins.
The use of NEM before acidification to prevent SH-group oxidation and disulfide
titration has also been applied on other systems, e.
tHcy and tCys in EDTA plasma were analyzed simultaneously by HPLC after the reduction of plasma disulfides
with tris(2-carboxyethyl)phosphine, precipitation of proteins with trichloroacetic acid, derivatization with 7-fluoro-2,1,3-benzoxadiazole-4-sulfonate (SBD-F), and fluorescent detection as described previously (10) using cystamine as an internal standard.
The improvement in silica dispersion when using NXT silane is said to lead to a decrease in filler-filler interactions compared to tetra sulfide (TESPT) or disulfide
(TESPD) silanes, according to the company.
a) Serum disulfide
bonds are reduced to release Hcy as monothiol;
3 /PRNewswire/ -- Orchid Biocomputer today announced that it has recently been issued United States Patent number 5837860, "Covalent Attachment of Nucleic Acid Molecules onto Solid-Phases via Disulfide
Bonds, by the U.
Brazzein's rigidity originates from four links called disulfide
bridges that lock in the protein's three-dimensional shape.
Stanyl NCU 014 is rubber modified; TW 275F6 is a 30% glass-filled grade with molybdenum disulfide
, NCU 002 and NCU 012 are PTFE-modified grades, the latter containing 30% glass fiber.
