# 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.

    <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>
