Comparison of compound data content in MetaCyc and KEGG
MetaCyc KEGG
Compounds 11991 15161
Compounds with structures 10546 14621
Compounds with comments 1486 2997
Mean comment length 47.69 6.51
Mean names per compound 2.37 1.62
Mean DB links per compound 1.71 3.71
Mean associated reactions 3.59 2.17
Mean associated pathways (all) per compound 1.78 0.67
Duplicate compounds 36 251

Compound entries in either DB may not have information on their chemical structures, and may not have comments describing the properties of the compound. Associated pathways of a compound include base pathways and superpathways in MetaCyc and KEGG maps and modules. Compounds were considered duplicates if they had identical standard InChI strings.
