Types Of Acids Flashcards
What are the three categories of acids
Fixed acid
organic acids
volatile acids
Fixed acids
Do not leave solution.
Once produced, they remain in body fluids until they are eliminated by the kidneys.
Sulfuric acid and phosphoric acid are the most important fixed assets in the body.
They are generated in small amounts during the catabolism of amino acids and compounds that contain phosphate groups, including phospholipids and nucleic acids
Organic acids
Take part in or are produced by cellular metabolism.
Important organic acids include lactic acid.
Under normal conditions, most organic acids are metabolized rapidly, so significant accumulations do not occur.
Volatile acid’s
Can leave the body and enter the atmosphere through the lungs
What important volatile acid forms spontaneously from carbon dioxide and water in body fluids
Carbonic acid
Enzyme carbonic anhydrase
Speeds up the process of creating carbonic acid. Enzyme is found in the cytoplasm of red blood cell’s, liver and kidney cells, parietal cells of the stomach, and many other types of cells.
What is the most important factor affecting the pH in your body tissues
The partial pressure of carbon dioxide (P⬇️CO2)
What happens to carbon dioxide in solution
Most is converted to carbonic acid, and most of the carbonic acid dissociates into hydrogen ions and bicarbonate ions.
The partial pressure of carbon dioxide and the pH are inversely related. In other words, when carbon dioxide levels increase
Additional hydrogen ions and bicarbonate ions are released, so the pH decreases
PH is a negative exponent, so when the concentration of hydrogen ions go up, the pH value
Goes down
As carbon dioxide leaves the bloodstream and diffuses into the Alveoli, The number of hydrogen ions and bicarbonate ions in the alveolar capillaries
Decreases, and blood pH increases.
