Question

, Nitrogen is an extremely important element for organisms, but so difficult to obtain when compared to getting C,H, and O. While ubiquitous in the atmosphere, the most common atmosphe a) (4pts.) Gi ric form is unusable by most organisms to make necessary organic compounds ve two classes of ORGANIC compounds which contain nitrogen (not inorganics like NH3!!) Describe each of their functions. (Note: a Polymer and its monomer do NOT count as TWO classes. Ex: Polysaccharides (cellulose) and monosaccharides (glucose) are the SAME class (saccharides!)

Explanation / Answer

The organic compounds contining nitrogen are

1. Aminoacids for example glycine and lysine etc contains nitrogen

Their function is protein formation. Which in turn forms muscle and various other structures in body.

2. Amides

They are formed from the reaction between amines amd carboxylic acids.

Function- nylon which is a fibre used in clothes is formed from hexamethylenediamine and adipic acid reaction.

3. Nitrogenous bases like purine and pyrimidines found in RNA and DNA.
