Study Notes
Bioelements Classification
- Primary Bioelements: These are the most abundant bioelements in living organisms, making up 99% of the organism's matter. They include carbon (C), hydrogen (H), oxygen (O), nitrogen (N), phosphorus (P), and sulfur (S).
- Primary Bioelements Function: These elements are the foundation of essential organic molecules in life, such as carbohydrates, lipids, proteins, and nucleic acids.
- Secondary Bioelements: Less abundant than primary bioelements, but still critical for functions in organisms. Secondary bioelements include calcium (Ca), sodium (Na), potassium (K), magnesium (Mg), chlorine (Cl), and iron (Fe).
- Secondary Bioelements Function: Essential for bone formation, nerve impulse transmission, maintaining fluid balance, and other organism functions.
- Trace (Olig) Elements: These bioelements are present in very low quantities, but are essential for proper organism functioning. Examples include copper (Cu), zinc (Zn), manganese (Mn), iodine (I), and cobalt (Co).
- Trace Element Function: Vital for enzyme activation, oxygen transport, and hormone production.
