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.
