Solubility of the Proteinogenic α-Amino Acids in Water, Ethanol, and Ethanol–Water Mixtures
The addition of organic solvents to α-amino acids in aqueous solution could be an effective method in crystallization. We reviewed the available data on the solubility of α-amino acids in water, water-ethanol mixtures, and ethanol at 298.15 K and 0.1 MPa. The solubility of l-alanine, l-proline, l-arginine, l-cysteine, and l-lysine in water and ethanol mixtures and the solubility of l-alanine, l...
متن کاملPermeability of cork for water and ethanol.
Transport properties of natural (noncompressed) cork were evaluated for water and ethanol in both vapor and liquid phases. The permeability for these permeants has been measured, as well as the sorption and diffusion coefficients. This paper focuses on the differences between the transport of gases' relevant vapors and their liquids (water and ethanol) through cork. A transport mechanism of vap...
متن کاملNMR-the basic principles and its use in studies of water/ethanol/mixture
NMR is the one of the most widely used and helpful spectroscopic technicque. It's theoritical parts depend on quantum physics, this technique has transformed the practice of chemistry.It's principle based on spin angular momentum and NMR interactions in a static magnetic field. Proton shows two orientations named α and β. When spins pulsed, spins are changed from one orientation to another. Aft...
متن کاملMaize response to water, salinity and nitrogen levels: yield-water relation, water-use efficiency and water uptake reduction function
Water, salinity and nitrogen are the major factors affecting maize production in arid and semi-arid areas. The objectives of this study were to investigate the effects of different water, salinity and nitrogen levels on yield-water relationships, water use, water productivity (WP), water use efficiency (WUE) and water uptake reduction function by maize hybrid SC-704 in a semi-arid area and ...
متن کاملBiochemical Markers of Acute and Chronic Ethanol Use: Forensic and Clinical Applications
Background: The analysis of ethanol in bio-samples is an important method for determination of acute alcohol use/abuse both in clinical and forensic toxicology. In forensic cases, it is known that micro-organisms involved in the postmortem putrefaction process can produce alcohol and when the body has been traumatized. In clinical setting, post-ingestion time has a critical role for determinati...
