The present study describes the rapid microplate method to determine pyruvic acid content in different varieties of onions. Onion juice was treated with 2,4-dinitrophenylhydrazine to obtain hydrazone, which was further treated with potassium hydroxide to get stable colored complex. The stability...
Various carbon materials, including activated carbon, flake graphite, carbon black and multiwall carbon nanotubes, were adopted as supports for lead-promoted platinum catalysts in the investigation of aqueous-phase oxidative dehydrogenation of lactic acid to produce pyruvic acid. Among them, the...
The purpose of this study is to assess some of the variables determining the aldol-like condensation of pyruvic acid (1), a peroxide scavenger, in aqueous solution to parapyruvic acid and higher oligomers. Its stability is compared to 3 other α-keto carboxylic acids, 2 with sterically hindered ...
Pyruvic acid (PA) exists in fogs, aerosols and clouds. The photochemistry-driven reaction pathways of PA in the aqueous phase are more elusive than the gas phase. The PA photochemical process may occur in the bulk liquid phase and at the air-liquid interface in ambient conditions. We conducted t...
The ability of different yeasts to synthesize pyruvic acid (PA) from glycerol-containing substrates has been studied. The selected strain Yarrowia lipolytica VKM Y-2378 synthesized PA with α-ketoglutaric acid (KGA) as a byproduct. The content of KGA greatly depended on cultivation conditions. T...
The conversion of biomass derivative 1,2-propanediol (PDO) to value-added chemicals by selective catalytic oxidation is of great research interest. Herein, we provide an alternative and effective strategy for selectively catalyzing the PDO oxidation to pyruvic acid using Sn(IV) doping MCM-41 (Sn...
Zinc (Zn) is known as a co-factor for over 300 metalloproteins or enzymes, and has essential roles in many physiological functions. However, excessively high Zn concentrations are induced in pathological conditions such as interruption of blood flow in stroke or transient global ischemia-induced...
Pyruvic acid is important organic chemical intermediates that plays a role in cardiomyocyte pathophysiology and therapy. This study sought to explore the inotropic effects of pyruvic acid on the function of the isolated rat hearts and investigate its underlying mechanism. Pyruvic acid produced a...
It is hypothesized that a novel crystalline solid dispersion (CSD) of docetaxel (C-DXT) can be engineered by dispersing native docetaxel (DXT, a BCS class II drug) in sodium acetate crystal (SA). DXT is dissolved in glacial acetic/SA solution and freeze-dried. The resulting C-DXT is characterize...
Sodium acetate trihydrate (SAT) can be used as phase change material in latent heat storage with or without utilizing supercooling. The change of density from liquid to solid state leads to formation of cavities inside the bulk SAT during solidification. Samples of SAT which had solidified from ...
BackgroundAt our institution, we began using sodium acetate for resuscitation of trauma patients in 2005. Sodium acetate is used as an alternative to normal saline to help prevent hyperchloremic metabolic acidosis as well as to help buffer metabolic acidosis.
Electrical nucleation was investigated by using a Ag anode with sodium acetate trihydrate crystals embedded on the surface in a supercooled aqueous solution of sodium acetate (45–54 wt%) as a latent heat storage device. Rapid electrical nucleation was achieved by applying a direct-current volta...
Electro-activated solutions of salts of weak organic acids are defined as novel potent disinfecting agents that can be used in the agri-food industry. The aim of the present work is to study and understand the destruction mechanism of electro-activated solutions of sodium acetate (EAA) and sodiu...
To reduce the energy consumption of buildings significantly, a novel solar combi-system with short and long-term heat storage has been developed. A system prototype with 22.4 m2 (aperture) evacuated tubular collectors, a 735 L water tank and 4 phase change material (PCM) units each containing 15...
ABSTRACTAcetate is a major source of energy and substrate for milk fat synthesis in the dairy cow. We recently reported a linear increase in milk fat yield and greater than a 30% net apparent transfer of acetate to milk fat with ruminal infusion of neutralized acetate. Additionally, ruminal acet...
Aggregated particles in supercooled solution of sodium acetate trihydrate (SAT) are revealed to consist of crystals of sodium acetate (SA) by X-ray diffraction measurements performed on a premise of non-anisotropy of crystals in the solution. Model calculations of crystal growth of SA suggest th...
Biodiesel production through transesterification reaction with methanol using calcium oxide (CaO) as a solid base catalyst is restricted due to the need to the high molar ratio of methanol to oil and long reaction time. Therefore, the CaO catalyst was modified by potassium acetate (PA) to prepar...
Fatty acid methyl ester (biodiesel) was developed from new non-edible feedstock oil, bitter almond oil (BAO) through transestefication with methanol using potassium acetate supported on activated carbon (PA/AC) as a solid base catalyst. Activated carbon was prepared from waste of polyethyleneter...
The kaolinite (Kaol) intercalated with potassium acetate (Ac) was prepared and characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and thermogravimetry. Molecular dynamic simulation was performed to investigate the structure of Kaol–Ac intercalation complex...
In this paper, the frost resistance of roller compacted concrete (RCC) mixed with rubber particles and steel fibers was investigated, 25% (by weight) potassium acetate (KAc) solution was the medium in freeze-thaw cycles. The mass loss, relative dynamic elastic modulus, microstructures, and pore ...
