How to Learn Vitamin B6 and Pyridoxal-5′-Phosphate Homeostasis: From B6 Vitamers to PDXK/PNPO, PLPHP, Mitochondrial PLP and Enzyme Cofactor Control
Distinct learning-progression job: Learn vitamin B6 as a family of interconvertible molecules whose active coenzyme, pyridoxal-5′-phosphate (PLP), must be produced, transported, buffered and delivered to enzymes without allowing too much reactive free PLP to accumulate. Canonical boundary: Heme Biosynthesis and Trafficking remains the owner of porphyrin/heme production; Sphingolipid Metabolism remains the owner of ceramide and…

How to Learn Methylglyoxal and the Glyoxalase System: From Triose-Phosphate Leakage to GLO1/GLO2, Dicarbonyl Stress, MG-H1 and Metabolic Quality Control
Distinct learning-progression job: Learn methylglyoxal as a reactive side-product of central metabolism whose formation, glutathione-dependent clearance, protein/DNA glycation and stress signalling reveal an important principle: metabolic pathways must manage chemically reactive by-products as well as useful products. Canonical boundary: Redox Biology and Oxidative Stress remains the broad owner of ROS, antioxidant networks and cysteine redox…

How to Learn Mitochondrial One-Carbon Metabolism: From Serine and SHMT2 to MTHFD2/MTHFD1L, Formate Export, Redox and Nucleotide Supply
Distinct learning-progression job: Learn mitochondrial one-carbon metabolism as a compartmentalised folate network that converts serine and glycine carbon into folate-bound one-carbon units, supports mitochondrial translation and redox chemistry, and exports formate to the cytosol for biosynthesis. Canonical boundary: Mitochondria and Mitochondrial Dynamics remains the broad owner of mitochondrial structure, fusion, fission and bioenergetics; Human Mitochondrial…

How to Learn Plant Nitrate Assimilation: From NPF/NRT Uptake to Nitrate Reductase, Plastid Nitrite Reduction, GS–GOGAT and Carbon–Nitrogen Balance
Distinct learning-progression job: Learn nitrate nutrition as one connected plant system: root uptake and sensing, whole-plant transport, cytosolic nitrate reduction, plastid nitrite reduction, ammonium incorporation through GS–GOGAT, and regulation by light, carbon status and nitrogen demand. Canonical boundary: Legume–Rhizobium Root Nodule Symbiosis remains the owner of symbiotic nitrogen fixation; Plant Photorespiration remains the owner of…
