Write a short note on Primary and secondary metabolites

1.	Write a short note on Primary and secondary metabolites
Answer» Primary MetabolitesThese are the chemical compounds produced during the\xa0growth and development, processes. They are also involved in the primary metabolic processes of respiration and photosynthesis. The\xa0primary metabolites are formed in the growth phase. They maintain the physiological functions of the body and are known as central metabolites. They are the intermediate products of anabolic metabolism, which are used by the cells for the formation of essential macromolecules.Secondary MetabolitesThese compounds are produced by the organisms that are not required for primary metabolic processes. However, they can be important ecologically or otherwise. Secondary metabolites are considered to be the end products of primary metabolites because they are derived by the pathways in which the primary metabolites involve.For eg., antibiotics, toxins, pheromones, enzyme inhibitors, etc. Streptomycetes and related actinomycetes are the sources of novel secondary metabolites.
