Monk fruit is a “suitable option” for sweetening food and drinks without raising blood sugar, Lisa Moskovitz, RD, CDN, CEO of ...

Branched-chain amino acids (BCAAs) may also be used as part of treatment, but they work in a different way. People with cirrhosis often have low levels of BCAAs. Taking BCAA supplements can help ...

One of the most elegant theories about the origins of life on our planet is that it was kick-started by a delivery from outer space. This idea suggests that prebiotic molecules—the building blocks of ...

Tryptophan, the essential amino acid behind the Thanksgiving myth that eating turkey can make you sleepy, has been found to exist on Bennu, a small asteroid that swings by our planet about every six ...

Researchers discovered that the common amino acid arginine can block harmful Aβ aggregation and reduce its toxic effects in Alzheimer’s disease models. In flies and mice, oral arginine lowered plaque ...

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 ...

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 ...

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 ...

Amino acids are absolutely essential to our health—and for life itself. They are the so-called “building blocks” of proteins. They play a key role in the growth, repair, and maintenance of almost ...

Rolls of brightly colored plastic. After it is used and discarded, polylactic acid could be used as a feedstock for making the amino acid alanine. Credit: Shutterstock One of the simpler amino acids, ...

The tumor microenvironment is not just a site of cancer growth—it is a high-stakes metabolic contest where tumor and immune cells vie for limited resources. Amino acids, once seen as passive nutrients ...

They turned to the amino acid glutamine, because it is the most abundant amino acid in the blood. Glutamine is naturally synthesized in the body and can also be consumed from all animal protein ...
