In a new study of mice, researchers have found that an experimental drug that breaks down the amino acid cysteine slows pancreatic tumor growth by causing ferroptosis, an unusual form of cell death. A ...

All proteins are built from the same 20 amino acids. One of these, cysteine, was assumed not to have been present at the origin of life. In a new study, scientists have recreated how cysteine was ...

Pennington Biomedical researchers have identified cysteine, a sulfur-containing amino acid, as a key factor in weight loss. The study, published in Nature Metabolism, reveals that calorie-restrictive ...

A diet rich in the amino acid cysteine may have rejuvenating effects in the small intestine, according to a new study from MIT. This amino acid, the researchers discovered, can turn on an immune ...

Scientists found that reducing cysteine can turn stored white fat into brown fat. Scientists in the United States have discovered a biological "switch" that could play a vital role in weight loss. The ...

Sulfur is the third most abundant mineral in your body. It is present in methionine and cysteine, which are two of the amino acids you use to make proteins. Both of these amino acids are present in ...
