<chem-struct-wrap> Chemical Structure Wrapper
Wrapper element for a chemical expression, reaction, equation, etc. that is set apart from the text; includes any number, label, or caption that accompanies the chemical expression.
A <chem-struct-wrap> may be numbered, programmatically, by a formatting application or by preserving the number inside a <label> element.
The chemical expressions inside this element may be formally tagged as <chem-struct> elements or merely expressed as one or more display objects.
The @position attribute may be used to indicate whether this element must be anchored at its exact location within the text or whether it may float (for example, to the top of the next page, into the next column, to the end of a logical file, or within a separate window).
NLM DTD Historical Note
This element (<chem-struct-wrap>) was significantly remodeled from previous versions of this Tag Set. The current NISO JATS values are backward compatible with all JATS versions and with the last NLM version, but not with earlier NLM DTD versions. Specifically, the <chem-struct-wrap> element replaces the <chem-struct-wrapper> element, which is no longer available.

With <caption> and alternative structures
... <chem-struct-wrap> <caption> <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> </caption> <alternatives> <graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="pq0209587032" specific-use="internet"/> <chem-struct>C<sub>6</sub>H<sub>12</sub>O<sub>6</sub> + 6 O<sub>2</sub> ⟶ 6 CO<sub>2</sub> + 6 H<sub>2</sub>O </chem-struct> </alternatives> </chem-struct-wrap> ...
