Scientists have identified a mirror-image form of the amino acid cysteine that selectively slows the growth of certain ...

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 ...

When scientists genetically engineered mice so that they could not generate an amino acid called cysteine, and then fed the mice a diet without any cysteine in it, the mice lost 30% of their body ...

A new research perspective was published in Aging, titled "Trioxidized cysteine and aging: a molecular binomial that extends far beyond classical proteinopathic paradigms." Oxidative stress ...

Mice genetically engineered to lack the ability to make the amino acid cysteine, and fed a cysteine-free diet, lost 30 percent of their body weight in just one week, a new study shows. Published ...

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 ...
