Hereafter a classification system was established to divide reactions in the whole metabolic network of A. oryzae into 7 main metabolic pathways: carbohydrate metabolism, energy metabolism, amino acid metabolism, nucleotide metabolism, lipid metabolism, cofactor metabolism and secondary metabolism.
Pharmacokinetic studies showed that oxidation, hydrolysis, and acyl migration of C-3′ and/or C-4′ positions in hepatic microsome are the main metabolic pathways in metabolism of praeruptorins [ 75, 76].
Three main metabolic pathways are highlighted here: citrate metabolism, linoleic acid metabolism and phenylpropanoids metabolism.
Furthermore, the main metabolic pathways represented were purine metabolism (49 sequences), pyrimidine metabolism (11), phosphatidylinositol signaling system (11) and inositol phosphate metabolism (10); these and other pathways observed are shown in Additional file 2: Table S3.
The housekeeping bacteria are required in all bacteria and are often major players in the main metabolic pathways including central carbon metabolism and amino acid synthesis.
In the lung, the main metabolic pathways affected are involved in energy metabolism (creatine, glucose, lactate, alanine, glutamate), protein synthesis (leucine) and membrane lipids (choline, phosphoethanolamine).
It is a member of the nuclear hormone receptor family, which influences whole-body energy homeostasis via three main metabolic pathways: adipocyte differentiation, insulin sensitivity, and lipoprotein metabolism.
(b) Transcriptional and enzyme level regulations of the main metabolic pathways.
Its main metabolic pathways in mammals are described in Fig. 2.
