KEGG functional annotations a) detailed representation of functional classes belonging to six main functional categories b) subcategories of carbohydrate, lipid, and amino acid metabolism. Functional categories: A Metabolism, B Genetic Information Processing, C Environmental Information Processing, D Cellular Processes, E Organismal Systems, F Human Diseases. R programming language [20] and ggplot2 [21] package were used to create the images based on KAAS-KEGG number of functional categories
