Attaching amino acids to a hydrophobic organic molecule allows them to self-assemble into rare, knotted structures with ...

The complex building blocks of life can form spontaneously in space, a new lab experiment shows.

Scientists studying dust and rock from asteroid Bennu say they are holding something close to a time capsule from before Earth was habitable. Locked inside the grains are amino acids, sugars and other ...

Proteins are the building blocks of life. These biomolecules comprise chains of amino acids that fold into precise shapes to ...

Cold cosmic dust grains can link amino acids into protein‑like chains in deep space, suggesting life’s chemistry may begin ...

Amino acids are molecules fundamental to living organisms because they combine to build proteins, the workhorses of the cell. One metabolic pathway that produces amino acids involves transamination, a ...

A study finds that proteinaceous amino acids, which are incorporated into protein chains by living organisms, more readily form short chains that resemble modern proteins than nonproteinaceous amino ...

Although the myriad proteins found in all life are largely built from a set of 20 amino acids, many other amino acids exist in nature, and it remains a curiosity as to why some were ultimately ...
