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

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

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

New experiments reveal that protein precursors can form naturally in deep space under extreme cold and radiation. Scientists found that simple amino acids bond into peptides on interstellar dust, long ...

The world is in the middle of a peptide drug revolution. These short chains of amino acids—the building blocks of ...

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 ...

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 ...

Life on Earth is complex and varied, but every living organism on the planet builds its proteins from the same set of 20 amino acids. All proteins in a human body, for example, are made up of some ...
