Mention two secondary metabolism useful for human welfare

1.	Mention two secondary metabolism useful for human welfare
Answer» 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.If one were to make a list of biomolecules, such a list would have thousands of organic compounds including amino acids, sugars, etc. For reasons that are given in topic Metabolic basis for living, we can call these biomolecules as metabolites. In animal tissues, one notices the presence of all such categories of compounds shown in Figure 1. These are called primary metabolites. However, when one analyses plant, fungal and microbial cells, one would see thousands of compounds other than these called primary metabolites, e.g. alkaloides, flavonoides, rubber, essential oils, antibiotics, coloured pigments, scents, gums, spices. These are called secondary metabolites
