उत्तर
\[\ce{CH2OH-CO-(CHOH)4-CH2OH}\] is an example of ketoheptose.
Explanation:
Ketoheptose → \[\begin{array}{cc}
\phantom{....}\ce{CH2 - OH}\\
|\phantom{.....}\\
\phantom{}\ce{C = O}\\
|\phantom{.....}\\
\phantom{..}\ce{(CHOH)4}\\
|\phantom{.....}\\
\phantom{...}\ce{CH2OH}
\end{array}\]
Aldohexose Glucose → \[\begin{array}{cc}
\phantom{}\ce{CHO}\\
|\phantom{....}\\
\phantom{...}\ce{(CHOH)4}\\
|\phantom{....}\\
\phantom{...}\ce{CH2OH}
\end{array}\]
Ketoheptose → Ketone group and 7 carbon present
Ketotetrose → Ketone group and 4 carbon present
