Functional Groups in Sugars
Sugars are a class of biomolecules that are important sources of energy for living organisms. They are made up of carbon, hydrogen, and oxygen atoms arranged in a specific way. There are two functional groups that are characteristic of sugars:
1. Carbonyl Group
The carbonyl group is a functional group that consists of a carbon atom double bonded to an oxygen atom (C=O). In sugars, this group can be found in two forms:
- Ketose sugars have a carbonyl group in the middle of the molecule.
- Aldose sugars have a carbonyl group at the end of the molecule.
2. Hydroxyl Group
The hydroxyl group is a functional group that consists of an oxygen atom bonded to a hydrogen atom (OH). Sugars have multiple hydroxyl groups that are attached to the carbon atoms of the molecule.
Characteristic Functional Groups
The two functional groups that are characteristic of sugars are:
1. Carbonyl Group
- Aldose sugars have a carbonyl group at the end of the molecule.
- Ketose sugars have a carbonyl group in the middle of the molecule.
2. Hydroxyl Group
- Sugars have multiple hydroxyl groups that are attached to the carbon atoms of the molecule.
Answer
The correct answer is option D, carbonyl and hydroxyl groups.
