Researchers have new insights into the citric acid cycle: Certain bacteria can use this central metabolic pathway 'backwards', but to do so they must have very high concentrations of the enzyme ...

FAYETTEVILLE, GA, UNITED STATES, July 2, 2025 /EINPresswire.com/ -- Researchers explore how 6-PPD quinone (6-PPDQ), an environmental contaminant derived from tire ...

The Krebs cycle, also known as the citric acid cycle, is a series of enzymatic reactions that releases energy from stored carbohydrates, fats, and proteins. The Krebs Cycle was first proposed by Hans ...

The Citric Acid CycleThe reductive citric acid cycle behaves like a chemical hurricane. Carbon atoms from CO 2 (yellow and orange) attach at either end of molecules. As the cycle proceeds ...

While testing a theory about how sugars formed on early Earth, researchers stumbled upon reaction conditions that produce tartrates, molecules closely related to others in a key metabolic cycle found ...

High carbon dioxide concentrations are required to allow the central metabolic pathway to run "backwards" / publication in "Nature" The citric acid cycle is an ...

Citric acid is a weak organic acid found in citrus fruits. It is a natural preservative and is also used to add an acidic (sour) taste to foods and soft drinks. In biochemistry, it is important as an ...
