<chem-struct>

Chemical Structure (Display)

A chemical expression, reaction, equation, etc. that is set apart within the text

Remarks

This element accommodates chemical reactions expressed in many ways: as text with emphasis tags, subscripts, and superscripts; as a preformatted area (<preformat>), as an included graphic, etc. The linking attributes may also be used to point to an external source such as a URI.

Display Note: A chemical structure is assumed to be anchored at its position within the text.

This element (<chem-struct>) has been significantly remodeled in version 3.0 of the Tag Set. The values and/or usage in version 3.0 are not backward-compatible with that in previous versions of the Tag Set. Specifically, in prior versions the <chem-struct> element was allowed inside the <app>, <app-group>, <body>, <boxed-text>, <disp-quote>, <fig>, <glossary>, <notes>, <ref-list>, <sec>, <supplementary-material>, and <table-wrap> elements; in those places, it has been replaced by the <chem-struct-wrap> element.

Only <license-p>, <named-content>, <p>, and <styled-content> elements can contain either <chem-struct> or <chem-struct-wrap>.

Conversion Note: For users of Elsevier Tag Sets, the list class elements can be used to express the <compound-info> element inside a chemical structure.

Related Elements

The expression of a chemical reaction or other chemical structure goes inside the <chem-struct> element. The related element <chem-struct-wrap> is an outer wrapper that may hold, for example, both a chemical reaction and its caption or three related chemical expressions.

<p>Chemical equation for the oxidation of glucose into
cardon dioxide and water. Unlike combustion, metabolic
pathways involving glycolysis and respiration control
the release of energy during oxidation, thereby permitting
its storage in ATP molecules.  This slow release of energy
via chain reactions with multiple steps can be grouped
into four stages.</p>
