The number on the label counts nitrogen. Your muscles count leucine, essential amino acids, and how much you absorb. Here is why 20 grams of collagen and 20 grams of whey are not the same meal.

Considering the roles of diet and supplements based on what happens to the body before a race, during the race, and after ...

A recent review published in the journal Cell Press Blue suggests that restricting specific amino acids may reproduce some of the metabolic benefits of protein restriction (PR), as observed mainly in ...

A new review examines how protein and specific amino acid restriction may affect metabolism, cellular aging, and longevity, ...

Biologists have long known that amino acids can help stabilize proteins, for example as additives to pharmaceutical formulations. In trying to understand why this works, EPFL and MIT researchers have ...

Nutrition can be complex for those with hectic schedules. Focusing on both protein quality and fiber intake is vital for a ...

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 ...

Proteins are built by mixing and matching amino acids, but researchers want to create new functions by adding noncanonical amino acids (ncAAs). However, this process often requires complex whole ...

A fruit-fly protein thought only to store amino acids in fact responds to nutritional deficiency in both development and adulthood, resulting in lifespan extension.
