Alongside antacids like Prilosec® and Nexium®, a new product, Puroast® Low Acid Coffee, may provide some relief this holiday season. Woodland, CA (PRWEB) November 04, 2011 The upcoming holiday season brings with it the traditional gift giving, travel to see family, savory food, hearty beverages and – “holiday heartburnâ€, that nasty reminder we’ve had too much of a good thing. But this year alongside antacids like...
Single amino acid exerts 'remote control' over double bond placement by desaturase enzymes Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and collaborators at the Karolinska Institute in Sweden have discovered how an enzyme "knows" where to insert a double bond when desaturating plant fatty acids. Understanding the mechanism — which relies on a single amino acid far from the enzyme's active site — solves a 40-year mystery of how these enzymes exert...
Nitrogen-containing soil is a source of hydroxyl radicals that remove pollutants from the atmosphere Eutrophication harms the environment in many ways. Unexpectedly, nitrogen fertilizer may also be positive for the environment. And even acidic soils, promoting the destruction of forests, can have a positive effect. Researchers from the Biogeochemistry Department at the Max Planck Institute for Chemistry in Mainz found out that nitrogen fertilizer indirectly strengthens the self-cleaning...
Material designed for energy applications is 10 times faster than natural enzyme, uses inexpensive metalsLooking to nature for their muse, researchers have used a common protein to guide the design of a material that can make energy-storing hydrogen gas. The synthetic material works 10 times faster than the original protein found in water-dwelling microbes, the researchers report in the August 12 issue of the journal Science, clocking in at 100,000 molecules of hydrogen gas every second.This...
Process utilizes filtering material designed for synthetic blood vesselsThough it may not sound very glamorous, a new method of extracting ammonium from liquid animal manure could be exciting news for both confined animal operations and environmental groups, according to a Texas AgriLife Extension Service engineer.The method uses gas-permeable membrane technology that tests have shown could remove 50 percent of the dissolved ammonium in liquid manure in 20 days. The removed ammonium is...
UC Merced professor coauthors paper published in Nature Chemistry, offering insight into how naturally occurring RNA precursors may have formed on Earth billions of years agoA relatively simple combination of naturally occurring sugars and amino acids offers a plausible route to the building blocks of life, according to a paper published in Nature Chemistry co-authored by a professor at the University of California, Merced.The study, "A Route to Enantiopure RNA Precursors from Nearly...

Los Alamos team sees unprecedented proof of ion's role in enzymatic processA Los Alamos National Laboratory research team has harnessed neutrons to view for the first time the critical role that an elusive molecule plays in certain biological reactions. The effort could aid in treatment of peptic ulcers or acid reflux disease, or allow for more efficient conversion of woody waste into transportation fuels.In a paper appearing this week in Angewandte Chemie International Edition, Los Alamos...

Acid rain is any form of precipitation that is unusually acidic, meaning that is possesses high levels of hydrogen ions. It can have harmful effects on aquatic animals, plants, and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules within the atmosphere to produce acids. Nitrogen oxides can be produced naturally by lightening strikes. Sulfur dioxide can be produced naturally by volcanic eruptions. The chemicals that are...
In chemistry, salt is a general term used for ionic compounds composed of positively charged cations and negatively charged anions, so that the product is neutral and without a net charge. These ions can be inorganic (Cl-) as well as organic (CH3-COO-) and monoatomic (F-) as well as polyatomic ions (SO42-). Solutions of salts in water are called electrolytes. Electrolytes as well as molten salts conduct electricity. Zwitterions are salts that contain an anionic center and a cationic...
