Amino acids serve as the monomeric units of proteins, act as precursors for neurotransmitters and hormones, and provide key intermediates for energy and one-carbon metabolism. At physiological pH they ...

Peptides occupy an increasingly significant position in modern biochemical research. These short chains of amino acids are ...

Proteins are the molecular machines that make all living things hum. They stop deadly infections, heal cells, capture energy from the sun and so much more. Proteins are built by stringing together ...

Researchers have developed an unnatural amino acid that can be incorporated into existing proteins to create new fluorescent proteins, which will be valuable in the study of protein–substrate ...

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 ...

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 ...
