It's a dogma taught in every introductory biology class: Proteins are composed of combinations of 20 different amino acids, arranged into diverse sequences like words. But researchers trying to ...

The traditional explanation of the initial genetic code in life seems less established when ancient proteins seem to be ...

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 ...

Amino acids are the monomeric compounds that combine to form proteins. Essential amino acids cannot be made by the body, so must come from our diet. The essential amino acids are not synthesized in ...

Evolution settled on a genetic code that uses four letters to name 20 amino acids. Synthetic biologists adding new bases to DNA will be free to improve on nature — if they can. With recent innovations ...

Essential amino acids are organic compounds that your body needs to function. You can get them from certain foods. Amino acids, often referred to as the building blocks of proteins, are compounds that ...

Researchers are building out the repertoire of chemical reactions, using light. They report a method using photobiocatalysis to produce non-canonical (not naturally occurring) amino acids that are ...

Researchers from ETH Zurich have modified a bacterial transport system so that it can efficiently introduce large quantities of unnatural amino acids into cells, disguised as a kind of Trojan horse.

Amino acids are the building blocks of protein. These molecules come together to form proteins. Your body uses them for many important functions, such as making hormones, building muscle, and ...
