About Biochemistry & Enzymes
Biochemistry is the study of chemical processes within living organisms. Enzymes are biological catalysts that accelerate biochemical reactions, making life possible. This resource covers the full scope of enzymology from individual enzyme pages to complete metabolic pathways.
Each enzyme page includes the EC number, recommended name, alternative names, catalytic activity (reaction equation), comments, and cross-references to UniProt. All data is sourced from the ENZYME nomenclature database (Expasy, SIB Swiss Institute of Bioinformatics) under CC BY 4.0.
