Question

Primary metabolise using in daily life

Answer 1

In addition to primary metabolites such as carbohydrates, amino acids, fatty acids, cytochromes, chlorophylls, and metabolic intermediates of the anabolic and catabolic pathways, which occur in all plants and where they all have the same metabolic functions, plants also produce a large variety of compounds.

Answer 2

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 summarizes the recent advances in the modification of a more specific secondary metabolism for the improvement of quality traits. Essential amino acid biosynthesis is strictly regulated by some key enzymes, such as dihydrodipicolinate synthase (DHDPS) in lysine (Lys) biosynthesis and anthranilate synthase in tryptophan (Trp) synthesis. Folate has received considerable attention, since its deficiency induces neural tube defects during early pregnancy. Fatty acids are another target for nutritional improvement because some of them are critical in metabolism, cardiovascular health, inflammatory responses, and blood pressure regulation.
