Proteins are the workhorses of cells and provide vital insights to cell health and disease function. Immunoassays and mass spectrometry are well established methods for studying proteins and have led ...

Scientists have uncovered how aging alters tryptophan metabolism in the brain, linking a longevity protein to ...

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 ...

Whether you’re interested in why a living system works as it does or the reasons it goes awry, proteins are a critical part of the molecular picture. The proteins circulating in a person’s plasma can ...

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 ...

Scientists at the University of California, Santa Cruz, have trapped the ribosome, a protein-building molecular machine essential to all life, in a key transitional state that has long eluded ...

When a bone grows, our bodies’ proteins help provide the structure. When a muscle tears, proteins help rebuild it. When we fight an infection, transport oxygen in our blood or send messages to a cell, ...

In a new study of people with long-term vegan diets, most ate an adequate amount of total daily protein, but a significant proportion did not meet required levels of the amino acids lysine and leucine ...

As people grow older, the same brain chemistry that once supported sharp thinking and stable mood can quietly start to work ...
