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

<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>
