A major protein inside the egg, called ovalbumin, possesses the sulfur-containing amino acid cysteine. When heated, these sulfur atoms are converted to hydrogen sulfide, the nasty gas associated with rotten eggs and bodily functions. It doesn't take much to wrinkle our noses.
A team of chemists demonstrated that they can identify the true animal source of leather goods by examining collagen. This technique could be enormously useful for investigating cases in which counterfeit leather goods are suspected.
Krypton and xenon serve practical and important purposes. But harvesting them from the air is energy intensive, as it requires a temperature of -300 degrees F. So chemists constructed a molecular sieve that easily separates the noble gases at room temperature.
Assuming that the company Ava is able to successfully replicate wine by simply combining chemicals in a laboratory, a big question still remains: Would people actually buy it? ACSH President Hank Campbell and Senior Fellow of Biomedical Science Dr. Alex Berezow debate the issue.
The presence of a molecule that strongly enhances the flavor of other molecules may explain why garlic powder is such a commonly used ingredient in cooked foods.
A group of researchers is attempting to make coffee roasting more science than art. The team wants to improve consistency by using the tools of analytical chemistry to monitor the coffee roasting process in real-time.
In an effort to clamp down on counterfeit food, a research group in Italy has devised a chemical test to help determine the authenticity of Parmigiano-Reggiano cheese. This is according to a report published in the Journal of Agricultural and Food Chemistry.
Nitrogen triiodide is exceedingly cool stuff. The purple solid is very easy to make, but you better keep it wet. Once dry, it's a powerful contact explosive which could theoretically be useful for practical jokes. I know, because I survived after someone played one on me.
Researchers at the University of California have been able to successfully create a liquid blood pressure medication that can be absorbed through the skin, without the requisite skin toxicity. The implications for transdermal drug delivery are multiple and profound.
