Natural Acids of Daily use

we use acids in daily life. They can be found within cells and digestive systems, occur naturally in foods, and are used for many common chemical reactions.

Acids

  1. Acetic Acid
    • Acetic Acid is a synthetic carboxylic acid with antibacterial and antifungal properties.
    • Its mechanism of action is not fully known, undissociated acetic acid may enhance lipid solubility allowing increased fatty acid accumulation on the cell membrane or in other cell wall structures.
    • Acetic acid, as a weak acid, can inhibit carbohydrate metabolism resulting in subsequent death of the organism.
  2. Citric Acid
    • Citric acid (citrate) is a weak acid that is formed in the tricarboxylic acid cycle or that may be introduced with diet.
    • The evaluation of plasma citric acid is scarcely used in the diagnosis of human diseases.
    • On the contrary urinary citrate excretion is a common tool in the differential diagnosis of kidney stones, renal tubular acidosis and it plays also a role in bone diseases. 
  3. Tartaric Acid
    • Tartaric Acid is a white crystalline dicarboxylic acid found in many plants, particularly tamarinds and grapes.
    • It is used to generate carbon dioxide through interaction with sodium bicarbonate following oral administration.
  4. Oxalic Acid
    • Formula C2H2O4 
  5. Lactic Acid
    • Lactic acid appears as a colorless to yellow odorless syrupy liquid.
    • Corrosive to metals and tissue.
    • Used to make cultured dairy products, as a food preservative, and to make chemicals.
  6. Methanoic acid / Formic acid
    • Formic acid appears as a colorless liquid with a pungent odor.
    • Flash point 156°F.
    • Density 10.2 lb / gal.
    • Corrosive to metals and tissue.
