Having considered localization of respiratory functions in mitochondria and in prokaryotic cells, it's time to return to the ...

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

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 ...

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 ...

The Krebs cycle is named after its discoverer, Hans Krebs. It is also known as the citric acid cycle or the tricarboxylic acid cycle. It is a series of chemical reactions required for cellular ...

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 ...

Long-chain fatty acid oxidation disorders (LC-FAODs) are rare, life-threatening, autosomal recessive genetic disorders characterized by acute crises of energy production and chronic energy deficiency.

Succinic acid, or butanedioic acid, was first isolated as long ago as 1546 as a distillate from amber. It also occurs naturally in fungi and lichens, and it is a component of the citric acid cycle.

Enzymes catalyze the critical chemical reactions that help build and power living organisms. But chemists studying the origin of life on Earth face a vexing question: How did these metabolic reactions ...
