Primary and secondary metabolites and their applications
Metabolites are the intermediates and products of metabolism. The term metabolite is usually restricted to small molecules. A primary metabolite is directly involved in normal growth, development
Secondary metabolites are frequently produced at highest levels during a transition from active growth to stationary phase. The produc er organism can grow in the absence of their synthesis, suggesting that secondary metabolism is not essential, at least for short term survival. A second view proposes that the ge nes involved in secondary
In contrast, secondary metabolites do not show a considerable change in their presence or absence in metabolic reactions. This is the main difference between primary and secondary metabolites. Both primary and secondary metabolite are small organic compounds. Reference: 1. “Primary and Secondary Metabolites – Boundless Open Textbook

Secondary Metabolites in Plants The apparent lack of primary function in the plant, combined with the observation that many secondary metabolites have specific negative impacts on other organisms such as herbivores and pathogens , leads to the hypothesis that they have evolved because of their protective value. Many secondary metabolites are toxic or repellant to herbivores and microbes
Secondary metabolites are one of their essential means of growth and defense, and these metabolites are readily available for discovery. Secondary metabolites with noteworthy biological activity are considered as an alternative to most of the synthetic drugs and other commercially valuable compounds.
Secondary metabolites, by virtue of their nature as idiosyncratic and of no vital significance to the producing organism, are often produced in very low yields by the original wild type strains. Indeed, as modern highly specific and sensitive screens to detect bioactive molecules have become available and as researchers have looked at ways to
There are some similarities between the pathways that produce primary and secondary metabolites, namely that the product of one reaction is the substrate for the next and the first reaction in each case is the rate-limiting step. Also the regulation of secondary metabolic pathways is interrelated in complex ways to primary metabolic regulation.

They are derived by unique biosynthetic pathways from primary metabolites and intermediates. Plant Secondary Metabolites • Biochemical pathways that are not necessary for growth
The boundary between primary and secondary metabolism is blurred. Based on their biosynthetic origins, plant natural products can be divided into three major groups: the terpenoids, the alkaloids, and the phenylpropanoids and allied pheno-lic compounds. All terpenoids, including both primary metabolites and more than 25,000 secondary compounds
inconsistent with their predicted amino acid sequences, and suggestive of post-translational modiﬁcation, are marked in yellow (primary metabolism) or red (secondary metabolism). Blue spots correspond to other examples of post-translational modiﬁcations that are mentioned in the text and in Table 3. Separations have been performed on
Plants produce a variety of compounds that can be divided into primary metabolites and secondary metabolites. Primary metabolites are essential for the survival of the plant and include sugars, proteins and amino acids. Secondary metabolites were once believed to be waste products. They are not essential to the plant’s survival, but the plant does suffer …
Primary metabolite because they are directly involved in normal growth, development, and reproduction. In other words, an organism would die without enzymes.
Primary metabolites as essential nutrients are being more intensively studied and their engineering has often been reviewed. Low molecular weight metabolites are important components of crop plants for both consumers and producers. Thus, this chapter first outlines the metabolic engineering of essential nutrients, such as essential amino acids, lipids, vitamins, and minerals, and then
The useful natural products are synthesized through secondary metabolism, hence they are also known as secondary metabolites (for microbial secondary metabolites see Secondary Metabolites).The secondary metabolites include alkaloids, terpenoids, tannins, glycosides (steroids and phenolics) and saponins.Their chief applications are in Pharmaceuticals, in food flavoring and perfumery (Collins

Basics of Primary and Secondary Metabolites
The vast and versatile pharmacological effects of medicinal plants are basically dependent on their phytochemical constituents. Generally, the phytochemical constituents of plants fall into two categories based on their role in basic metabolic processes, namely primary and secondary metabolites. Primary plant metabolites are involved in basic life functions; therefore, they are more or less
The key difference between primary and secondary metabolites is that primary metabolites are the end products of metabolism that directly participate in normal growth, development and reproduction of an organism while secondary metabolites are the metabolites that do not directly participate in normal growth, development and reproduction of an organism.
The examples of secondary metabolites are alkaloids, tannins, resins, gums, latex, etc. CONCLUSION Though plants produce these byproducts of primary and secondary metabolites for their own use, man found the usage of these chemicals for his own benefits.
