Metabolic pathway diagram showing various biochemical processes such as glycerol metabolism, Calvin cycle, and serine cycle. Includes pathways for amino acid biosynthesis and fatty acid synthesis/degradation. Arrows indicate the flow between different compounds and cycles, with specific intermediates like 3HP-CoA, 2H3MV-CoA, and 3-Hydroxyacyl-CoA labeled throughout. The diagram is color-coded to distinguish different metabolic pathways and cycles. — Main metabolic pathways of PHA generation (Adapted from Choi et al., 2020).
