A deep insight into the diverse metabolic pathways gives us the possibility to find the similarities among those processes. This manuscript provides a new paradigm for chemical education using leucine metabolism as the example. Referring concepts from other disciplines, we generalized and summarized the chemical principles involved in the biological metabolisms. Further, patterns and causation behind the predominance of specific metabolic processes were explored through the comparison among homologous enzymes in different pathways to ascertain their evolutionary similarity. This comparison and contrast are intended to help students in summarizing general principles between distinct metabolic pathways, deepening their understanding towards involved metabolic pathways, and preventing the misconception over so-called "chaotic" biochemical metabolic processes. As an attempt of reform in basic biochemistry and bioengineering curricula upon the topic of metabolism, we hope the manuscript can promote students' sense of intrigue, wonder, and curiosity.
- Leucine,
- Tricarboxylic acid cycle,
