Primary and Secondary Metabolites

  • The term metabolite applies to a small molecule which is either an intermediate or product of metabolism.
  • Primary metabolites are organic compounds that are directly involved in the development process of an organism.
  • They are found in all animals and plants cells.
  • They play roles in the physiological processes.
  • For example, amino acids, sugars etc. are primary examples
  • Secondary metabolites basically occur in fungal, plant and microbial cells. 
  • They are not directly involved in metabolic activities and perform assistive functions.
  • For example, alkaloids prevent the parasitic attack, flavonoids attract pollinators,  involved in UV filtration, symbiotic nitrogen fixation and floral pigmentation. 
  • Other examples include oils, rubber, gums, latex etc.
