The key idea behind our framework is that life produces molecules with purpose, while nonliving chemistry does not. Cells ...

The findings, which detail how amino acids shaped the genetic code of ancient microorganisms, shed light on the mystery of how life began on Earth. "You see the same amino acids in every organism, ...

One of the most elegant theories about the origins of life on our planet is that it was kick-started by a delivery from outer space. This idea suggests that prebiotic molecules—the building blocks of ...

Researchers demonstrated how amino acids could spontaneously attach to RNA under early Earth-like conditions using thioesters, providing a long-sought clue to the origins of protein synthesis. This ...

Doubly stapled α-helix consisting only of achiral amino acids. Its one-handed form can be isolated because the interconversion between the right- and left-handed forms is almost completely suppressed.

Amino acids are organic compounds that serve as the fundamental building blocks of proteins. They play a crucial role in the structure, function, and regulation of the body's tissues and organs. Amino ...

MIT researchers have found that amino acids — major building blocks for life on Earth — are stable in highly concentrated sulfuric acid. Their results support the idea that these same molecules may be ...
