**Introduction**
The glucose and galactose are known as aldoses because they have ___ functional group at their C1 position, whereas fructose is a ketose sugar because it has a ketone group at ___ position.
**Glucose, Galactose, and Fructose Molecules are Isomers**
The images above depict the structural formulas of glucose, galactose, and fructose, illustrating how these molecules are isomers of each other. Each molecule consists of a six-carbon backbone, but the arrangement of atoms and functional groups differ, giving each sugar unique properties.
**Structural Analysis**
1. **Glucose (Glikoz)**
- Glucose is presented with a hexagonal ring structure. The hydroxyl groups (-OH) and hydrogen atoms (H) are attached to the carbon atoms in a specific manner. The functional groups and their positions are crucial for identifying glucose as an aldose.
2. **Galactose (Galaktoz)**
- Similar to glucose, galactose has a hexagonal ring with hydroxyl groups and hydrogen atoms attached to the carbon atoms. Galactose is also an aldose, sharing a similar functional group at the C1 position as glucose, but differing in the orientation of the hydroxyl groups.
3. **Fructose (Fruktoz)**
- Fructose is depicted with a five-membered ring structure including an oxygen atom, making it different from glucose and galactose. Fructose is a ketose sugar with its ketone functional group at the C2 position.

1. a) Ketone; C1
2. b) Alcoholic; C2
3. c) Aldehyde; C1
4. d) Carboxyl; C6
To summarize, glucose and galactose have an aldehyde functional group at their C1 position, categorizing them as aldoses, while fructose has a ketone functional group at the C2 position, classifying it as a ketose. Understanding these differences is pivotal in the study of carbohydrate chemistry and metabolism.
Definition Definition Organic compounds that have a carbonyl group, C = O, as their functional group. The carbonyl group in ketones is placed somewhere in the middle of the molecular structure, which means, the C=O is attached to two alkyl groups or benzene rings. Just like all other homologous series, the naming of ketones is done using a common suffix “-one”. The general molecular formula is C n H 2n O. Functional group of a ketone
