If you took biochemistry classes, chances are good you remember memorizing the Krebs cycle, a well-known metabolic pathway in which sugars are converted through a series of steps to generate ATP, a ...

The Krebs cycle may be like a busy roundabout, as vehicles whizz in and out from different junctions Transformer: The deep chemistry of life and death Nick Lane Profile Books IF WE want to ...

The Krebs cycle represents a common meeting place of carbohydrate, lipid, and protein metabolism. It variously serves as a means to produce energy, generate intermediates, and convert molecules ...

Two simple molecules can react to form most of the intermediates in an analog of the modern-day Krebs cycle, without the need for enzymes or metals, according to a new study (Nat. Chem. 2020, DOI ...

Markus A. Keller, Domen Kampjut, Stuart A. Harrison, Markus Ralser. Sulfate radicals enable a non-enzymatic Krebs cycle precursor. Nature Ecology & Evolution, 2017; 1: 0083 DOI: 10.1038/s41559-017 ...

Unfinished cycle However, the enzyme-free Krebs cycle that Ralser observed isn’t the complete biochemical cycle as it operates in modern cells. That may have come later, after enzymes evolved.

What would be the perfect revenge for a scientist whose paper is turned away from Nature? A Nobel Prize, of course. Such was the case for Hans Krebs, the biochemist who nabbed the award in 1953 for ...
