<chem-struct>

Chemical Structure (Display)

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/Formatting Note: A chemical structure is assumed to be anchored at its position within the text.
Historical Note: This element (<chem-struct>) was significantly remodeled from previous versions of this Tag Set. The current NISO JATS values are backward compatible with the last NLM version, but not with earlier versions. 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 elements; in each of those places, it has been replaced by the <chem-struct-wrap> element.
Elsevier 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>
