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.
Can u answer both please
1. **Explanation of the Diagram:**
- The diagram illustrates the Haworth projection of D-mannose.
- The cyclic structure consists of a six-membered ring (a pyranose form). This is indicated by the carbons 1 through 6.
**Structure Details:**
- **Carbon 1 (C1):** This is the anomeric carbon in the ring structure on which the OH group can be either above (beta) or below (alpha) the plane of the ring.
- **Carbon 2 (C2), Carbon 3 (C3), and Carbon 4 (C4):** Each of these carbons has an OH group attached.
- **Carbon 5 (C5):** This carbon atom is bonded to a CH2OH group.
- **Carbon 6 (C6):** Located outside the ring, attached to the CH2OH group.
2. **Question Options:**
- A) alpha
- B) beta
- C) gamma
- D) delta
3. **Identifying the Anomer:**
- The configuration around the anomeric carbon (C1) in the Haworth projection specifies the anomer.
- The structure shown depicts the OH group on C1 below the plane of the ring, indicating the alpha (α) anomer of D-mannose.
**Answer:** A) alpha
This educational information helps students understand the structural representation of carbohydrates and how to determine the specific anomer of a sugar from its Haworth projection.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F9804a76a-010d-4c52-ac1e-3d3df2595288%2Fd4c4455a-e837-4ba3-bbb8-d8ee2869d9cd%2Fct8rglh_processed.jpeg&w=3840&q=75)
