====== Reactions ======

In enviPath, reaction objects represent biotransformation reactions from educt compound(s) to product compound(s). Reactions are directly linked to the involved [[compounds|compounds]]. A link from a rule to a reaction indicates that a reaction is in agreement with the generalized biotransformation rule.

Additionally, meta-information like experimental conditions or enzymes can be stored with a reaction. Enzyme information can be used to link out to enzyme databases such as KEGG or BRENDA.

=====Available reactions =====


A list of all available reactions is provided here: http://envipath.org/reaction. To view all reactions of a particular package, select the package first, then the reactions within this package (http://envipath.org/package/<id>/reaction).

=====Creating a reaction =====


Reactions can be created manually by drawing them with the [[https://lifescience.opensource.epam.com/ketcher/|Ketcher chemical structure editor]] or by providing the [[https://daylight.com/dayhtml_tutorials/languages/smirks/|SMIRKS.]]

Alternatively, reactions are created during Pathway prediction, where each edge in the pathway corresponds to a reaction.
