The image shows the molecular structure of a chemical compound, represented as a line drawing with arrows and numbers. The structure consists of four carbon atoms arranged in a tetrahedral shape, with two hydrogen atoms attached to each carbon atom. One of the carbon atoms is attached to a hydroxyl group (-OH) and another is attached to a hydrogen atom (-H). The remaining two carbon atoms are attached to each other by single bonds (-C-C). The compound is denoted by the chemical formula C6H12O6, or hexose for short.
