Barium hydroxide may be used in the development of formulations for the purification of materials such as heteropolysaccharide-protein biopolymers and the release of long-chain bases (LCB) from biological samples. Barium hydroxide solution may be used for protein precipitation in turbid fluids such as whole blood in assays based on the Somogyi-Nelson method.
Used in conjunction with zinc sulfate to deproteinize via barium sulfate precipitation whole blood, plasma, or serum samples which are colored or turbid. The resulting supernatant or filtrate is then available for subsequent analysis of glucose by Somogi-Nelson method.
Natural biopolymers from plant sources contain many impurities (e.g., fat, protein, fiber, natural pigment and endogenous enzymes), therefore, an efficient purification process is recommended to minimize these impurities and consequently improve the functional properties of the biopolymer. The main objective
A rapid, facile, and sensitive uv-spectrophotometric assay has been developed for the determination of the enzymatic degradation of polysaccharides that generates reducing sugars. The assay was carried out with 2-cyanoacetamide in a single test tube. The solution was left at

The beta-elimination of phosphoserine residues by dilute alkali is catalysed by the presence of group II metal ions. The use of 0.1 M-Ba (OH)2 catalysed the rate of beta-elimination of phosphoserine by more than two orders of magnitude compared with
Desflurane, enflurane and isoflurane can be degraded to carbon monoxide (CO) by carbon dioxide absorbents, whereas sevoflurane and halothane form negligible amounts of CO. Carbon monoxide formation is greater with drier absorbent, and with barium hydroxide, than with soda lime.
The alkylation of cyclomalto-oligosaccharides (cyclodextrins, CDs) with dialkyl sulfate-barium hydroxide has been claimed to yield 2,6-di-O-alkyl derivatives. Re-investigation by plasma desorption-m.s. of the products of laboratory methylation of alpha CD, beta CD, or gamma CD and ethylation of beta CD
