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.
![### Glycosidic Linkage Identification
#### Glycosidic Linkage Diagram
The diagram above illustrates a disaccharide consisting of two monosaccharides joined by a glycosidic linkage. The structural formula shows the specific orientation and connection between the sugar molecules.
#### Multiple Choice Question
**This is a:**
Please select the correct type of glycosidic linkage present in the disaccharide shown above:
- [ ] 1-4-α glycosidic linkage
- [ ] 1,4-β glycosidic linkage
- [ ] 1,2-α glycosidic linkage
- [ ] 1,2-β glycosidic linkage
### Explanation
In the diagram, the type of glycosidic linkage is determined by the position of the carbon atoms involved in the bond (indicated by positions such as 1,4 or 1,2) as well as the orientation (alpha or beta). Identifying the linkage involves examining the anomeric carbon (the carbon derived from the carbonyl group in the sugar) and the carbon it is attached to in the second sugar unit.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F71f58b2f-7cf4-442d-8d68-410e9206b661%2F2cd6f61b-9cd9-46c8-9002-ddc207bf8fd5%2Fc7paei_processed.jpeg&w=3840&q=75)
![### Polymer Classification Exercise
**Question:**
Is this a homo- or hetero-polymer?
[ Polymer Structure Diagram ]
The displayed diagram is a chemical structural representation of a polymer. It shows a long chain of repeating units consisting of carbon (C), hydrogen (H), oxygen (O), and nitrogen (N) atoms. The chemical structure features a sequence of repeating segments, each containing a carbonyl group (C=O) and an amide bond (NH).
**Answer Choices:**
Please select one of the following options:
- Homo-polymer
- Hetero-polymer](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F71f58b2f-7cf4-442d-8d68-410e9206b661%2F2cd6f61b-9cd9-46c8-9002-ddc207bf8fd5%2Fg5cydqm_processed.jpeg&w=3840&q=75)
