Citrate

Citrate (pronounced as /ˈsɪtreɪt/) is a key component in the metabolism of all aerobic organisms. It is a form of citric acid, a weak organic acid that has the chemical formula C6H8O7.

Etymology

The term "citrate" is derived from the Latin word citrus, which means "lemon". This is because citric acid was first isolated from lemon juice by the Swedish chemist Carl Wilhelm Scheele in 1784.

Function

Citrate plays a crucial role in the citric acid cycle, also known as the Krebs cycle or the tricarboxylic acid cycle. This cycle is a series of chemical reactions used by all aerobic organisms to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins into carbon dioxide and chemical energy in the form of adenosine triphosphate (ATP).
