Question

What functional groups are in glucose?

Answer 1

Functional group:

The functional group may be defined as an atom or group of atoms joined in a specific manner that is responsible for the characteristic chemical properties of the organic compounds.

• Examples of functional groups are the hydroxyl group $(–\mathrm{OH})$, aldehyde group $(–\mathrm{CHO})$, and carboxylic acid group $(–\mathrm{COOH})$.

Structure of glucose:

• Glucose is the simplest sugar having molecular formula ${\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6$.
• It is made up of six carbon units known as hexose and it contains five hydroxyl groups $(–\mathrm{OH})$ and one aldehyde group $(–\mathrm{CHO})$.
