A structural formula is a representation of the arrangement of atoms within a molecule. It shows how atoms are connected by bonds and may indicate the spatial orientation of atoms in three-dimensional space.

Structural formulas are crucial for understanding the specific chemical properties and reactivity of organic molecules.
They can be depicted as Lewis structures, which show all valence electrons, or as skeletal formulas, which omit certain details for simplicity.
In microbiology, understanding structural formulas helps in identifying functional groups critical to microbial metabolism.
The structural formula provides insights into possible isomerism where compounds have the same molecular formula but different arrangements.
Biochemical pathways often rely on the recognition of specific structural formulas to understand enzyme-substrate interactions.
