Explanation of terms used by DrugBank

Reaction Type

In DrugBank, a reaction type is a short name or descriptor that generally describes what occurs to a substrate at a molecular level in a chemical or metabolic reaction in order to produce a product(s) or metabolites. Metabolic reactions curated in DrugBank are typically described as proceeding via particular reaction types, and a number of such reaction types are listed in DrugBank. Particular reaction types differ depending on what drug substrate(s) and enzymes are involved in the specific reaction.

For example, the reaction type 'hydroxylation' in DrugBank refers to a metabolic reaction that essentially proceeds by adding a hydroxyl (-OH) group to the reacting substrate to produce a resultant product or metabolite.
