Classifying Monosaccharides
Classify the monosaccharide shown as an aldose or a ketose, and name it according to its number of carbon atoms.

\begin{matrix}&& H& &H&&OH&&H&&OH&&O\\&&|&&|&&|&&|&&|&&||\\ HO&-&C&-&C&-&C&-&C&-&C&-&C&-&H\\&& |&&|&&|&&|&&|\\&& H&&OH&&H&&OH&&H \end{matrix}

ANALYSIS First determine if the monosaccharide is an aldose or a ketose. Then determine the number of carbon atoms present. This monosaccharide is an aldose because an aldehyde group is present. It contains 6 carbon atoms.
