IB BIO TOPIC 3.2 : CARBOHYDRATES, PROTEINS & LIPIDS Flashcards
Distinguish between organic and inorganic compounds (°3)
- Compounds containing carbon that are found in living organisms are regarded as organic.
- Exceptions :
Carbonates (ex. CaCO3)
Hydrogen Carbonates (ex. HCO3)
Oxide of Carbon (ex. CO, CO2)
- All other compounds are regarded as Inorganic.
