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
- 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.
- 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.
- 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.
- Oxalic Acid
- Formula C2H2O4
- 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.
- 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.
