  2. Citric acid - Wikipedia

    en.wikipedia.org/wiki/Citric_acid

    A citrate is a derivative of citric acid; that is, the salts, esters, and the polyatomic anion found in solutions and salts of citric acid. An example of the former, a salt is trisodium citrate; an ester is triethyl citrate. When citrate trianion is part of a salt, the formula of the citrate trianion is written as C 6 H 5 O 3− 7 or C 3 H 5 O ...

  3. Potassium citrate - Wikipedia

    en.wikipedia.org/wiki/Potassium_citrate

    Potassium citrate (also known as tripotassium citrate) is a potassium salt of citric acid with the molecular formula K 3 C 6 H 5 O 7. It is a white, hygroscopic crystalline powder. It is odorless with a saline taste. It contains 38.28% potassium by mass. In the monohydrate form, it is highly hygroscopic and deliquescent.

  4. Acetyl-CoA carboxylase - Wikipedia

    en.wikipedia.org/wiki/Acetyl-CoA_carboxylase

    Bicarbonate is deprotonated by Glu296, although in solution, this proton transfer is unlikely as the pKa of bicarbonate is 10.3. The enzyme apparently manipulates the pKa to facilitate the deprotonation of bicarbonate. The pKa of bicarbonate is decreased by its interaction with positively charged side chains of Arg338 and Arg292.

  5. Sodium citrate - Wikipedia

    en.wikipedia.org/wiki/Sodium_citrate

    It is also used as an anticoagulant for laboratory testing, in that blood samples are collected into sodium citrate-containing tubes for tests such as the PT (INR), APTT, and fibrinogen levels. Sodium citrate is used in medical contexts as an alkalinizing agent in place of sodium bicarbonate, [2] to neutralize excess acid in the blood and urine ...

  6. Calcium citrate - Wikipedia

    en.wikipedia.org/wiki/Calcium_citrate

    Calcium citrate is the calcium salt of citric acid. It is commonly used as a food additive , usually as a preservative, but sometimes for flavor. In this sense, it is similar to sodium citrate. Calcium citrate is also found in some dietary calcium supplements (e.g. Citracal or Caltrate). Calcium makes up 24.1% of calcium citrate (anhydrous) and ...

  7. Citrate test - Wikipedia

    en.wikipedia.org/wiki/Citrate_Test

    Use of citrate involves the enzyme citrate lyase, which breaks down citrate to oxaloacetate and acetate. Oxaloacetate is further broken down to pyruvate and carbon dioxide (CO 2). Production of sodium bicarbonate (NaHCO 3) as well as ammonia (NH 3) from the use of sodium citrate and ammonium salts results in alkaline pH. This results in a ...

  8. Bicarbonate - Wikipedia

    en.wikipedia.org/wiki/Bicarbonate

    The bicarbonate ion (hydrogencarbonate ion) is an anion with the empirical formula HCO − 3 and a molecular mass of 61.01 daltons; it consists of one central carbon atom surrounded by three oxygen atoms in a trigonal planar arrangement, with a hydrogen atom attached to one of the oxygens.

  9. Club soda - Wikipedia

    en.wikipedia.org/wiki/Club_soda

    A private-label-brand club soda as seen in Canada. Club soda is a form of carbonated water manufactured in North America, commonly used as a drink mixer. Sodium bicarbonate, potassium sulfate, potassium bicarbonate, potassium citrate, or sodium citrate is added to artificially replicate constituents commonly found in natural mineral waters [1] and offset the acidity of introducing carbon ...
