Study Notes
Separation Techniques
- Separation techniques are used to isolate and identify the different components of a living tissue extract.
Carbon Compounds
- Organic compounds make up the building blocks of living tissues.
Ash
- After oxidizing all the carbon compounds in a destructive experiment, inorganic mineral content remains, referred to as ash.
Elemental Analysis
- Elemental analysis reveals the precise composition of the elements in living tissues, including carbon, hydrogen, oxygen, and nitrogen.
Weighing and Drying
- Weighing a small amount of living tissue and drying it allows determination of the water content, revealing the proportion of water within living matter.
