Study Notes

Mineral Supply and Classification

  • Mineral supply depends on intake related to the composition of food
  • Minerals remain as ash after combustion of plant and animal tissues

Mineral Classification

  • There are three classes of minerals: main elements, trace elements, and ultra-trace elements
  • Main elements (intake > 50 mg/day): Ca, Cl, K, Mg, Na, P, S
  • Trace elements (concentrations < 50 mg/day): Fe, F, Co, Cu, Cr, I, Zn, Se, Mn, Mo, Ni
  • Ultra-trace elements (vital elements): Al, As, B, Ba, Bi, Br, Cs, Cd, Ge, Hg, Li, Pb, Rb, Si, Sn, Sb, Sr, Ti, W

Nutritional and Functional Roles

  • Sodium: essential for sodium absorption
  • Potassium: regulates osmotic pressure within the cell and is involved in cell membrane function
  • Calcium: essential for the formation of bones and teeth in some body tissues
  • Chloride: serves as a counter ion for sodium in extracellular fluid and for hydrogen ions in stomach acid
  • Phosphorus: essential nutrient and plays an important role in metabolism in the form of phosphate
  • Iron: essential ingredient of daily diet, present in hemoglobin (blood) and myoglobin (muscle tissue), and plays a crucial role in oxygen transport
  • Copper: component of oxidoreductase enzymes, catalyst in many unwanted reactions, and Cu2+-Ions are superoxide-bearing with a threshold value of 2.4-3.
