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 ...

A pore smaller than one nanometer reads peptide sequences amino acid by amino acid, pinpointing single-site Alzheimer's ...

Researchers have detected for the first time a molecule closely related to an amino acid: amino acetonitrile. A lot of attention is given to the quest for so-called "bio"-molecules, especially ...

In the early days of molecular evolution, one of the most tantalizing findings was the observation that protein sequence change seemed to occur at a rate proportional to the time since the ...

The nucleic acids of DNA encode genetic information, while the amino acids of proteins contain the code to turn that information into structures and functions. Together, they provide the two ...

From the 1950s to 1970s, discovery of enzymes began by identifying new chemical reactions within cell-free extracts, but ...
