Hyperpolarised carbon-13 imaging uses an injectable solution containing a ‘labelled’ form of the naturally occurring molecule pyruvate. The pyruvate enters the cells of the body, and the scan ...

Accurate interpretation of electrolyte blood results is key to patient diagnosis and management. Read our guide.

For roughly a century, ever since Alexander Fleming's accidental discovery of penicillin in 1928, fungi have proven to be a ...

The Stach Group in Penn Engineering has led a collaborative team identifying how chemical catalysts drive the creation of ...

A team of chemists has unveiled a novel method to simplify the synthesis of piperidines, a key structural component in many pharmaceuticals. The study combines biocatalytic carbon-hydrogen oxidation ...

Deubiquitinases (DUBs) are enzymes used by cells to trim protein modifications made from the protein ubiquitin, and thereby regulate proteins. Malfunctioning of DUBs could lead to diseases, including ...

Glycolysis and the tricarboxylic acid cycle are perhaps the most ancient metabolic pathways, and various of their intermediates (e.g., 2-oxoglutarate, succinate, pyruvate, and 3-phosphoglycerate ...

An early mention of palmitic acid in the chemical literature came in an 1879 report by Thomas Carnelley* and W. Carleton Williams at Owens College (Manchester, UK; eventually the University of ...

But James Watson and Francis Crick's claim was a valid one, for they had in fact discovered the structure of DNA, the chemical that encodes instructions for building and replicating almost all ...
