Amino acids are the building blocks of proteins, which control practically all cellular processes within our ... The stereochemistry of the alpha-carbon is established by the hydride transfer.

The authors add, "All known life uses a specific stereochemistry: left-handed amino acids and right-handed DNA. Understanding how this evolved is a long-standing mystery key for understanding the ...

The researchers found that amino acids—simple, abundant molecules on early Earth—can actively promote the polymerization of RNA under mild, prebiotic conditions. advertisement.

Scientists are making a case for adjusting our understanding of how exactly genes first emerged. For a while, there’s been a consensus about the order in which the building-block amino acids ...

Dry state oligomerization of nucleoside 2′,3′-cyclic phosphates catalyzed by amino acids. Credit: Nature Communications (2025). DOI: 10.1038/s41467-025-60359-3 ...

Amino acids, which are a key ingredient of life, could have originally been made in interstellar molecular clouds like that from which the solar system formed, before winding up in asteroids that ...

Intravenous amino acids increase kidney perfusion and recruit renal functional reserve. However, the efficacy of amino acids in reducing the occurrence of AKI after cardiac surgery is uncertain.

Branched-chain amino acids (BCAAs) are a group of three essential amino acids. Research suggests that BCAAs can improve muscle mass and exercise performance. They may also benefit people with ...
