Biochemical Pathways in the Biosynthesis of Pharmacologically Active Secondary Phytometabolites
Abstract: Plants are the main storage house of most food products, medicines, and nutritional supplements that exist. There are basically two kinds of phytochemicals in plants: these include primary and secondary metabolites. Primary metabolites play a crucial role in the biological functioning of plants because they play a major role in the processes of mitosis, respiration, metabolism, growth, and reproduction. Secondary metabolites are not just mere by-products of primary metabolism in …
