Study Notes
Classification of Minerals
- Minerals are essential for normal growth and maintenance of the body, and have a well-defined chemical composition and a specific crystal structure.
- There are two types of minerals: major minerals (macro minerals) and trace minerals (micro minerals).
- Major minerals are required by the body in large quantities (> 100 mg/day).
- Trace minerals are required by the body in small quantities (< 100 mg/day).
Examples of Minerals
- Major minerals: Calcium, Magnesium, Phosphorus, Sodium, Potassium, Chloride, and Sulfur.
- Trace minerals: Iron, Iodine, Copper, Manganese, Zinc, Molybdenum, Selenium, and Fluoride.
Clinical Significance of Minerals
- Normal levels of minerals in the body: Calcium (9.0-11.0 mg/dL), Magnesium (1.8-2.2 mg/dL), Phosphorus (3.0-4.0 mg/dL), Sodium (136-145 mmol/L), Potassium (3.5-5.0 mmol/L), and Chloride (96-106 mmol/L).
- Abnormal levels of minerals can lead to various health problems:
- Hypocalcemia (low Calcium level), Hypercalcemia (high Calcium level)
- Hypomagnesemia (low Magnesium level), Hypermagnesemia (high Magnesium level)
- Hypophosphatemia (low Phosphorus level), Hyperphosphatemia (high Phosphorus level)
- Hyponatremia (low Sodium level), Hypernatremia (high Sodium level)
- Hypokalemia (low Potassium level), Hyperkalemia (high Potassium level)
- Hypochloremia (low Chloride level), Hyperchloremia (high Chloride level)
