Polar Amino Acids: These amino acids have side chains that are hydrophilic and can form hydrogen bonds with water. Examples include serine, threonine, cysteine, asparagine, and glutamine. Non-Polar ...

Scripps researchers have developed a new paradigm for simply introducing non-canonical amino acids to proteins. Their strategy, disclosed in Nature Biotechnology on September 11 th, 2024, involves ...

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 ...

Nine essential amino acids—histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine—are available only through foods or supplements.

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 ...

Among non-essential amino acids, tyrosine is unique in that it is the only one that is produced from an essential amino acid, phenylalanine. Tyrosine plays a crucial role in the production of ...
