Bioelements

Different chemical elements essential for a species' normal development.

Primary Bioelements

The most abundant elements in living organisms (CHONPS: carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur).

Secondary Bioelements

Elements needed for osmotic balance and metabolic processes (Ca, Na, K, Cl, Mg, Fe, I).

Oligoelements/Micronutrients

Essential elements found in very small amounts (0.5%) in organisms; not all organisms need them all.

Study Notes

Bioelements

  • Bioelements are the chemical elements needed for a species to develop normally.
  • Primary bioelements (CHONPS) are carbon (C), hydrogen (H), oxygen (O), nitrogen (N), phosphorus (P), and sulfur (S). These make up about 95% of living matter.
  • Secondary bioelements (Ca, Na, K, Cl, Mg, Fe, I) are necessary for osmotic balance and metabolism, comprising about 4.5% of living matter.
  • Trace/Micronutrients (like Fluorine - F, Copper - Cu, Zinc - Zn, Cobalt - Co) are present in small amounts (around 0.5%) and have specific roles in the organism.

Primary Bioelements (CHONPS)

  • Carbon (C): crucial for building organic molecules.
  • Hydrogen (H): essential for many biological functions.
  • Oxygen (O): plays a vital role in metabolic processes.
  • Nitrogen (N): important component of proteins and nucleic acids.
  • Phosphorus (P): critical for energy transfer and DNA structure.
  • Sulfur (S): a key component of certain amino acids and proteins.

Secondary Bioelements (e.g., Ca, Na, K, Cl, Mg, Fe, I)

  • Calcium (Ca): essential for structure and function of bones and teeth.
  • Sodium (Na): involved in nerve impulse transmission.
  • Potassium (K): crucial for muscle function and nerve impulse transmission.
  • Chlorine (Cl): plays a role in maintaining fluid balance.
  • Magnesium (Mg): involved in many enzymatic reactions.
  • Iron (Fe): vital for oxygen transport.
  • Iodine (I): necessary for hormone production.

Trace/Micronutrients (e.g., Fluorine - F, Copper - Cu, Zinc - Zn, Cobalt - Co)

  • Fluorine (F): strengthens tooth enamel.
  • Copper (Cu): stimulates the immune system.
  • Zinc (Zn): regulates protein and lipid metabolism, involved in insulin formation, important for the immune system and membrane stabilization.
  • Cobalt (Co): involved in testosterone production.
