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 ...

Researchers in Japan have developed an electrical method that tells mirror-image forms of amino ...

But in Earth’s environment, most proteins don’t last nearly that long. That’s because organisms have evolved a handful of ...

A twelve-year prospective study identifies a serum essential amino acid pattern, higher methionine and threonine with lower ...

Amino acids are organic compounds that serve as the fundamental building blocks of proteins. They play a crucial role in the structure, function, and regulation of the body's tissues and organs. Amino ...

Researchers demonstrated how amino acids could spontaneously attach to RNA under early Earth-like conditions using thioesters, providing a long-sought clue to the origins of protein synthesis. This ...

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 new GeroScience study in lubber grasshoppers shows that intermediate rates of leucine catabolism, measured by carbon-13 ...

How did you discover MCBAs? Bile acids were first described chemically in 1849, and Heinrich Wieland was awarded a Nobel Prize in 1927 for comprehensively describing their chemistry. This description ...
