What are primary and secondary metabolites ? State its importance and components with examples.

Explanation

The most exciting aspect of chemistry deals with isolating thousands of compounds, small and big, from living organisms, determining their structure and if possible synthesising them.
In the list of Biomolecules, thousands of organic compounds including amino acids, sugars are found these biomolecules are called .metabolites..
In animal tissues, organic coinpuunds with row molecular weight arc found, they are called primary metabolites.
If one analyses the plant, fungal and microbial cells, thousands of other components are found e.g. alkaloides, flavonoides, rubber, essential oils, antibiotics, coloured pigments, scents, gums, spices etc. these are called secondary metabolites.
Primary and Secondary Metabolites :

We do not at the moment, understand the role or functions of all the .secondary metabolites. in the host organisms.
Primary metabolites have identifiable functions and play known roles in normal physiologial processes.
Many of the secondary metabolites are useful to .human welfare. (e.g., rubber, drugs, spices, scents and pigments).
Some secondary metabolites have ecological importance.
