C 9 BIOMOLECULES
142 BIOLOGYT here is a wide diversity in living organisms in our biosphere. Now aquestion that arises in our minds is: Are all living organisms made of thesame chemicals, , elements and compounds? You have learnt inchemistry how elemental analysis is performed. If we perform such ananalysis on a plant tissue, animal tissue or a microbial paste, we obtain alist of elements like carbon, hydrogen, oxygen and several others andtheir respective content per unit mass of a living tissue. If the same analysisis performed on a piece of earth s crust as an example of non-living matter,we obtain a similar list. What are the differences between the two lists?
fraction. Therefore elemental analysis gives elemental composition of living tissues in the form of hydrogen, oxygen, chlorine, carbon etc. while analysis for compounds gives an idea of Element % Weight of Earth’s crust Human body Hydrogen (H) 0.14 0.5 Carbon (C) 0.03 18.5 Oxygen (O) 46.6 65.0 Nitrogen (N) very little 3.3 Sulphur (S) 0.03 0.3
