Abstract Deep eutectic solvents (DESs) have been considered as novel and economic alternatives to traditional lubricants because of their similar physicochemical performance. In this study, choline chloride (ChCl) DESs were successfully synthesized via hydrogen-bonding networks urea thiourea the hydrogen bond donors (HBDs). The as-synthesized ChCl-urea ChCl-thiourea had excellent thermal stabil...

The maximum choline esterase activity of the superior cervical ganglion of the cat was measured and found to be, on the average, equivalent to the splitting of 0.10gamma of acetyl choline chloride per second per milligram of fresh tissue at a pH of 7.4 and 38 degrees . The least possible time required for destruction of the ester liberated by one nerve impulse was calculated to be 0.015sigma. T...

Choline chloride produced a dose-dependent induction of alkaline phosphatase activity in HeLa cells. At the highest concentration tested, 40 mM, there was a 5- to 7-fold increase in alkaline phosphatase activity, a significantly greater induction than that produced by equiosmolar additions of either NaCl or sucrose. Enzyme activity was higher than control values by 24 hr after the addition of t...

Four trials were conducted with a total of 188 crossbred sows to determine the effect of feeding diets supplemented with tallow (0 or 8%) and choline chloride (220 or 770 mg/kg diet) prior to parturition and during lactation on preweaning pig performance. On d 100 of gestation, sows were allotted to four factorially arranged dietary treatments: 0% tallow-220 mg/kg choline chloride, 0% tallow-77...

Female Sprague-Dawley rats received approximately 300 mg/kg per day of choline chloride through their drinking water on days 11 of pregnancy through birth and the level of nerve growth factor (NGF) in the hippocampus and frontal cortex of their male offspring was measured at 20 and 90 days of age. Prenatal choline supplementation caused significant increases in hippocampal NGF levels at 20 and ...

The use of cellulose-containing agricultural by-products modified with the cross-linking reagent dimethyloldihydroxyethylene urea (DMDHEU) and the quaternary amine, choline chloride, as anion exchange resins, has not been reported. The objective of the present study was to convert the readily available by-products, soybean hulls, sugarcane bagasse and corn stover to functional anion exchange re...

This work used a literature search to select the most suitable system for delignification process of annual plants. was evaluated in terms lignin removal from plant biomass. Based on previous experiments, low transition temperature mixture (LTTM) used, which choline chloride and lactic acid molar ratio 1:2. Samples hemp fibers were examined. The biomass monitored by changing content main compon...

This study aimed to evalúate the palatability, nutrient digestibility, metabolisable energy (ME) and faecal characteristics of diets in dogs fed increasing levels herbal phosphatidylcholine (herbal mix) versus an unsupplemented diet (with only 377 mg choline provided by 1 kg food) or chloride1 (2000 choline/kg 40 adult dogs. In experiment 1, a palatability test was conducted make two pairwise ...

α-Amino nitriles are synthesized in a one-pot, three-component coupling of aldehydes (or ketones), aniline, and trimethylsilyl cyanide using a catalytic amount of choline chloride.2ZnCl2 as a bio Lewis acidic ionic liquid. Mild Lewis acidic characteristic of this ionic liquid allows efficient synthesis of α-amino nitriles from acid sensitive aldehydes.
