The previous article described how fatty acids consist of long chains of carbon-carbon bonds, with the carbon mostly “saturated” with hydrogen atoms. When two saturated adjacent carbon atoms exchange ...

Decades after scientists discovered hundreds of different fatty acids in vegetable oils, two that had managed to elude detection have finally revealed themselves. The discovery may be the first of its ...

For more than 50 years, it has been suspected that fat cells constantly remodel the lipids they store. Researchers have now demonstrated this process directly for the first time using culture cells.

Fat is the bane of many diets, but it's an essential macronutrient—it's no less mandatory than the protein we need to eat. It plays a variety of functions in the body. It's a source of energy ...

Citric acid is a weak acid that is found naturally in all citrus fruits. Unlike strong acids, weak acids ionize only partially when in solution. If you’ve ever sunk your teeth into a lemon or any ...

While humans have an esthetic liking for symmetry in everything, nature prefers asymmetric, single-handed forms when it comes to amino acids—the building blocks of proteins, and, by extension, all ...

NASA's Curiosity Rover has discovered long carbon chains on Mars. On Earth, molecules like these are overwhelmingly produced by biological processes. When you purchase through links on our site, we ...

While the presence of these molecules is not proof of ancient life on Mars, scientists say it shows we could detect chemical signatures of past life, if it ever existed. When you purchase through ...
