Proteins are among the most important molecular building blocks of life. They are chains of amino acids assembled in our cells by ribosomes, the molecular "protein factories" of our bodies. The ...

Researchers at ETH Zurich recently explained the role of a molecular complex that orchestrates the production of proteins in our cells. They now show that this complex also controls the processing of ...

"Bread only for breakfast, light for lunch, and a big serving of meat for dinner." Many people likely find that their protein ...

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.

A new PLOS Pathogens study shows that the interferon-induced GTPase GBP7 unexpectedly promotes HSV-1 infection by activating ...

A newly developed luciferase-based reporter can detect problems in protein translocation and disulfide bond formation in the endoplasmic reticulum (ER). Inspired by natural mechanisms found in ...

A new review examines how protein and specific amino acid restriction may affect metabolism, cellular aging, and longevity, while highlighting important gaps in the human evidence.

The board certified physician and licensed boxer discusses muscle preservation, GLP 1 medications, and why Quest’s “Feed Your Athlete” campaign reflects his approach to everyday performance.

Is there a limit to how much protein your body can use from one meal? The answer may surprise you. Protein is a vital nutrient. It makes up our muscles, organs and skin cells. Our bodies can make some ...
