This template creates subunits of a biochemical reaction. For example, three instances of it were used to demonstrate the reaction of catalase.

The template is based on the <div> element, rather than tables, and this allows it to be more flexible in its display. For example, "2 × Hydrogen peroxide" is likely to wrap across multiple lines, but this doesn't force all the other headers to expand to match. Some of the formatting is dependent on the user's browser supporting the flexbox layout system; the vast majority do, but you will see slight differences in spacing on legacy browsers, although efforts have been made to provide a fallback.

The second example shows the same code, but constrained to 200 px wide; the content wraps, which is particularly useful for longer pathways and mobile devices.

Example code

[edit]
 <div style="display: flex; flex-flow: row wrap; width:300px; max-width: 100%">
 {{Biochem_reaction_subunit|compound=Hydrogen peroxide|image=Hydrogen-peroxide-3D-balls.png|n=2}}
 {{Biochem_reaction_subunit|enzyme=Catalase|for_prod=2 H<sub>2</sub>O}}

 </div>

Parameters

TemplateData for Biochem reaction subunit

This creates a subunit of a reaction: either chemical, or a reaction arrow with an enzyme and minor products or reactants. It is also possible to display custom content. It is designed to be placed inside a <div> tag with "display: flex; flex-flow: row wrap;", but it does work without flexbox.
Enzyme nameenzyme
The name of the enzyme. This may contain wikicode, but if it does or is otherwise not an article name, link must be specified.
Compound namecompound
The compound. This may contain wikicode, but if it does or is otherwise not an article name, link must be specified.
Title stylestyle
Custom styling for the title.
Number of moleculesn
Number of molecules of the given reactant relative to the others.
Custom titletitle
The title of the box; causes link to be ignored. Not required; use compound, enzyme and/or link if possible.
Forward minor substratefor_subst
The forward minor substrate(s). Can be formatted.
Example
H<sub>2</sub>O
Forward minor productfor_prod
The forward minor product(s). Can be formatted.
Example
H<sub>2</sub>O
Reaction directiondirection
Either forward, reverse or reversible: the direction of reaction.
Default
Forward
Reverse minor substraterev_subst
The reverse minor substrate(s). Can be formatted.
Example
H<sub>2</sub>O
Reverse minor productrev_prod
The reverse minor product(s). Can be formatted.
Example
H<sub>2</sub>O
Image sizeimagesize
The width of the compound or arrow image.
Default
100px for compounds, 75px for arrows
Example
55px
Compound imageimage
An image of the compound. Required for compounds.
Alternative contentother_content
If neither compound nor enzyme is specified, the content of the main part of the box.
Example
+
Reverse enzymeenzyme_reverse
Equivalent to enzyme but displayed below the arrow.
Compound (lower)compound_lower
Equivalent to compound but displayed below the arrow.
Title (lower)title_lower
Equivalent to custom title but displayed below the arrow.

Default value requires type
