A new understanding of transfer RNA biology means researchers can assign up to 34 codons to amino acids of their choosing ...

The amino acid arginine helps keep the human body humming, most notably by synthesizing proteins that carry out a range of cellular processes. It's produced by our bodies and found in common ...

A diet rich in the amino acid arginine might help the immune system fend off cancer and infection. In mice, eating a high-arginine diet quashed colon tumors and offered protection against the flu and ...

As Charlene Valledor, cosmetic chemist and co-founder of SOS Beauty explains, amino acid hair treatments are typically designed to strengthen and smooth hair by filling in the gaps in the cuticle and ...

A Salk Institute study found that a simple dietary amino acid, methionine, dramatically improved survival in mice facing severe infections and inflammatory conditions. Rather than directly targeting ...

One of life's many mysteries is how it ended up choosing only a set of 20 amino acids to build proteins for its wide catalog of organisms, from single-celled bacteria to behemoth whales. From a ...

Nearly all known life builds proteins from the same alphabet of 20 canonical amino acids. Strung together in different orders, those building blocks form the proteins that make cells work. In a new ...

I wonder if the pre-LUCA ribosome itself might have been radically different before we fixed on 20 amino acids? Obviously the protein scaffolding would be different, but also it could afford to be a ...

The genetic code is central to life. With minor variations, everything uses the same sets of three DNA bases to encode the same 20 amino acids. We have discovered no major exceptions to this, leading ...
