Proteins are among the most important molecular building blocks of life. They are chains of amino acids assembled in our cells by ribosomes, the molecular "protein factories" of our bodies. The ...

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 ...

To ensure that protein production in our cells runs smoothly, the protein complex NAC slows down the rate of protein ...

Tryptophan, the essential amino acid behind the Thanksgiving myth that eating turkey can make you sleepy, has been found to exist on Bennu, a small asteroid that swings by our planet about every six ...

A four–amino acid peptide called CAQK has shown powerful brain-protective effects in animal models of traumatic brain injury. Delivered through a standard IV, it zeroes in on injured brain tissue, ...

“Copper peptides are a type of carrier peptide made up of copper bound to amino acids, which are the building blocks of ...

A new study finds that at least one Archaea has surprisingly flexibility when interpreting genetic code, which goes against a ...

Every cell depends on proteins to function and stay healthy. These proteins are made inside the cell from amino acids but ...

The research shows for the first time that this compound, which consists of four amino acids, can produce therapeutic effects in brain injuries on its own, without requiring the administration of any ...

Proteins are biopolymers of amino acids (polypeptides), joined by peptide bonds, that are generated by ribosomes. The amino acid sequence, encoded by its gene, determines a protein’s structure and ...
