Each particle is on its own and they are far apart, arranged in a random way… If it was made of molecules, they would be in clusters of two or more. A compound is a pure substance that is made ...

The molecules may be remnants of fatty acids, which form cell membranes in Earth’s organisms, though they might have formed through a non-biological process ...

The Curiosity rover detected the largest organic molecules to date on Mars, which may be fragments of fatty acids, or some of ...

Materials scientists are measuring the rolling friction of tiny, micrometer-sized particles. These measurements permit them to better understand everyday products such as concrete.

Curiosity has previously discovered small organic molecules on Mars, but these recently found compounds are larger and would have require chemistry to reach a more advanced state to be produced.

The Mars Curiosity rover’s onboard mini-lab has helped confirm the existence of the largest organic molecules ever found on the Red Planet. The trio of long-chain compounds preserved in Martian ...

This compound was neither a protein nor lipid nor ... Nucleic acids are macromolecules, which means they are molecules composed of many smaller molecular units. Thes units are called nucleotides ...
