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 ...

The citric acid cycle is an important metabolic pathway that enables living organisms to generate energy by degrading organic compounds into carbon dioxide (CO?). The first step in the cycle is ...

HOW Does 6-PPDQ disrupts the citric acid cycle in caenorhabditis elegans. FAYETTEVILLE, GA, UNITED STATES, July 2, 2025 /EINPresswire / -- Researchers explore how 6-PPD quinone (6-PPDQ), an ...

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 ...

Citric acid naturally occurs in citrus fruits. Synthetic versions are produced from a type of mold and are often used as an additive. They can cause adverse reactions in some people. Citric acid is ...

Proceedings of the Royal Society of London. Series B, Biological Sciences, Vol. 140, No. 901 (Jan. 15, 1953), pp. 497-506 (11 pages) It has been suggested that the toxicity of fluoroacetate is due to ...

Lemons owe their signature tang to citric acid, yet the molecular mechanisms governing its accumulation have long remained a mystery. Now, a pioneering study has shed light on the epigenetic ...

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 ...

Citric acid is an important natural compound that has been known since the late 18th century. The pioneering Swedish–German chemist Carl Wilhelm Scheele isolated it from lemon juice in 1784. It has ...
