Depending on the origin and function, metabolites can be divided into two major categories; namely, Primary and Secondary metabolites.

Metabolism is the collection of chemical processes that occurs in living organisms in order to maintain life. Thousands of chemical compounds are involved in the metabolism of living organisms. These compounds are called metabolites and they are intermediates and products of metabolism.

17.1C: Primary and Secondary Metabolites

Primary and secondary metabolites are often used in industrial microbiology for the production of food, amino acids, and antibiotics. Bacterial metabolism can be classified into three major categories: the kind of energy used for growth, the carbon source, and the electron donors used for growth. Pathogenic bacteria are capable of exhibiting various types of metabolism. Metabolites, the intermediates and products of metabolism, are typically characterized by small molecules with various functions. Metabolites can be categorized into both primary and secondary metabolites.

Difference Between Primary and Secondary Metabolites

Raja and Ramasamy Vijayakumar. Reviewed: June 26th Published: September 5th Secondary Metabolites - Sources and Applications. The metabolism can be defined as the sum of all the biochemical reactions carried out by an organism. Metabolites are the intermediates and products of metabolism and are usually restricted to small molecules.

Primary and secondary metabolisms are coextensive; they can occur at the same time in the same cell and draw carbon-containing intermediates from the same sources. Generally, though, as nutrients are depleted the rate of growth slows and eventually stops. The progress of metabolism is correspondingly altered and a number of special biochemical mechanisms appear or become amplified to establish what is called secondary metabolism. The resultant secondary metabolites seem to be unnecessary for normal growth of the organism, but rather appear to be aimed at functions such as intercellular communication and defence and competition with other organisms. Secondary metabolism is a common feature of fungi. These later stages of secondary metabolism are so varied that individual secondary metabolites can have a narrow species distribution. The majority of secondary metabolites have their origins in a small number of the intermediates in pathways dealt with above:.

12 Difference Between Primary And Secondary Metabolites With Examples

The metabolites which are required for the growth and maintenance of cellular function are called primary metabolites , while such metabolites which are not required for the growth and maintenance of the cellular functions and are the end products of the primary metabolism are called as secondary metabolites. These products are classified as the primary and secondary metabolites. The primary metabolites consist of the vitamins, amino acids, nucleosides and organic acids, which are necessary at the time of logarithmic phase of microbial growth. But the products like alkaloids, steroids, antibiotics, gibberellins, toxins are the secondary metabolite compound produced during the stationary phase of the cell growth.

A primary metabolite is a kind of metabolite that is directly involved in normal growth, development, and reproduction. It usually performs a physiological function in the organism i. A primary metabolite is typically present in many organisms or cells. It is also referred to as a central metabolite, which has an even more restricted meaning present in any autonomously growing cell or organism. Some common examples of primary metabolites include: lactic acid , and certain amino acids.

Plant growth regulators can be classified as both primary and secondary metabolites due to their role in plant growth and development. Primary metabolites are microbial products produced continuously during the exponential phase of growth and are involved in primary metabolic processes such as respiration and photosynthesis. They include intermediates and end-products of anabolic metabolism, which are used by the cell as building blocks for essential macromolecules e.
