Citric acid is primarily found in citrus fruits, especially lemons and limes. The amount of acidity can be estimated by a fruit's taste, so fruits with high amounts of citric acid taste more sour. Citric acid is also found in most berries, including cranberries, black currants, red currants, raspberries and strawberries.Full Answer >
Clinton Community College explains that pyruvate is converted into acetyl coenzyme A before entering the citric acid, or Krebs, cycle. A carbon atom is removed from each of the two molecules of pyruvate, yielding acetyl coenzyme A and carbon dioxide. Pyruvate is produced during the first stage of cellular respiration, known as glycolysis. During the process of converting pyruvate to acetyl coenzyme A, six adenosine triphosphate molecules are produced.Full Answer >
The melting point of citric acid is 156 degrees Celsius or 313 degrees Fahrenheit. The molecular formula of citric acid is C6H8O7. It has a molar mass of 192.12 grams per mole.Full Answer >
The pH of citric acid is 2.2. pH measures the acidity and alkalinity of a substance or solution. The lower the number, the higher the acidity. The greater the number, the higher the alkalinity. On the scale, 7 is neutral.Full Answer >
