Amino acids have long been known to improve the stability and solubility of proteins. Amino acids might be added to insulin, for example, to maintain shelf-life and stop undesired chemical reactions ...

In the earliest phase of creating human proteins, the protein complex NAC performs an essential task by starting the first ...

Dementia is an umbrella term for several age-related disorders that can cause cognitive problems such as dysfunction in communication, attention, memory, reasoning, or problem solving; it includes ...

The first amino acid, discovered in 1806, had a disarmingly ordinary source: asparagus juice. Hence the name asparagine. The next amino acids to be discovered had sources that were, if anything, even ...

For decades, amino acids have been added to medical formulations like insulin as stabilizers: these small molecules keep proteins (i.e. larger particles) from interacting in undesirable ways. And for ...

Take a typical fish out of the water and it won't live long. It gets the oxygen it needs from the water it swims in. In a ...

New chemistry, new enzymology. With a new method that merges the best of two worlds — the unique and complementary activities of enzymes and small-molecule photochemistry — researchers at UC Santa ...

The coded amino acids each have unique properties that help biological proteins fold optimally. The set of amino acids biology uses appears to have been evolutionarily optimized. Disclaimer: AAAS and ...
