63 pathways to rebuild step by step
Each link opens the pathway as a board: place the intermediates and enzymes in order, with cofactors shown. See also the map of how the pathways connect.
Glucose to energy, the cycle that burns acetyl-CoA, and the cycle that disposes of nitrogen
How cells build the 20 amino acids, grouped by the metabolite each family branches from
Made from pyruvate, the end product of glycolysis
Made from 3-phosphoglycerate, a middle compound of glycolysis
Made from oxaloacetate, a compound of the Krebs cycle
Made from α-ketoglutarate, a compound of the Krebs cycle
Made from phosphoenolpyruvate and erythrose 4-phosphate through chorismate
Made from PRPP and ATP
How cells build the building blocks of RNA and DNA
Adenine and guanine nucleotides, built on a ribose phosphate
Uracil, cytosine and thymine nucleotides
DNA building blocks made from the ribonucleotides, and the kinases that charge the nucleotides
How cells reuse the bases and how purines and pyrimidines are broken down
Folate carries one carbon units; S-adenosylmethionine carries methyl groups
