Carbohydrates
Carbohydrates are the organic compounds that are obtained in foods and living matters in the shape of sugars, cellulose, and starch. The general formula of carbohydrates is Cn(H2O)2. The ratio of H and O present in carbohydrates is identical to water.
Starch
Starch is a polysaccharide carbohydrate that belongs to the category of polysaccharide carbohydrates.
Mutarotation
The rotation of a particular structure of the chiral compound because of the epimerization is called mutarotation. It is the repercussion of the ring chain tautomerism. In terms of glucose, this can be defined as the modification in the equilibrium of the α- and β- glucose anomers upon its dissolution in the solvent water. This process is usually seen in the chemistry of carbohydrates.
L Sugar
A chemical compound that is represented with a molecular formula C6H12O6 is called L-(-) sugar. At the carbon’s 5th position, the hydroxyl group is placed to the compound’s left and therefore the sugar is represented as L(-)-sugar. It is capable of rotating the polarized light’s plane in the direction anticlockwise. L isomers are one of the 2 isomers formed by the configurational stereochemistry of the carbohydrates.
![**Monosaccharide Reaction Prediction**
**Objective:**
Predict the product of each monosaccharide oxidation reaction. Modify the molecule accordingly, ensuring that atoms or bonds are added or removed as necessary.
**Reaction A:**
1. **Starting Molecule:**
- Structure: Linear chain of carbon atoms with hydroxyl (OH) groups and a carbonyl (C=O) group at the top.
- Composition:
- Top carbon: Double-bonded oxygen (C=O) and one hydrogen (H).
- Chain:
- First carbon after the top: Attached to one hydrogen (H) and one hydroxyl (OH).
- Next two carbons: Each attached to one hydrogen (H) and one hydroxyl (OH).
- Bottom carbon: Attached to two hydrogens (H2), forming CH2OH.
2. **Reaction Type:**
- Oxidation of the aldehyde group (C=O at the top).
3. **Predicted Product:**
- Structure: Similar linear chain, but the aldehyde group is oxidized.
- Composition:
- Top carbon: No changes to the carbonyl group; continues to have double-bonded oxygen and one hydrogen.
- Remaining chain remains unchanged in structure.
**Diagram Explanation:**
- There are tools for selecting, drawing, and modifying the molecule.
- Atoms and bonds can be adjusted through provided options like C (carbon), O (oxygen), and H (hydrogen).
- Visualization aids understanding of molecular changes during reactions.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4dbd844a-5288-4e1f-bdaf-b70c666aee4d%2F118fcd28-4705-420f-81f6-bd86966c81b4%2Fipg8f6n_processed.jpeg&w=3840&q=75)
