Template:Biochem reaction arrow alt text

reaction arrow

Template documentation[view] [edit] [history] [purge]

This template creates suitable alt text for the Biochem reaction arrow Y XXXX horiz/vert med.svg series of images. It takes parameters in the same order as the images, so the alt text for

[[File:Biochem reaction arrow forward YYNN horiz med.svg]]

is

{{Biochem reaction arrow alt text|forward|subst|prod|||horiz}}

Note that subst and prod can be any values here, so if you get passed a substate on an optional parameter p, you can pass {{{p|}}} directly to this template, and the arrow will only be mentioned if the parameter is passed and non-blank. The result for this example is

Rightward reaction arrow with minor substrate(s) from top left and minor product(s) to top right
