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.

![## Reaction Mechanism Exercises
### Problem 1
**Reactants:**
- A benzylic alcohol is reacted with acetic anhydride in the presence of sulfuric acid (H₂SO₄).
**Explanation:**
- The reaction likely involves the formation of an ester. The acid catalyzes the reaction, enabling the alcohol to attack the carbonyl carbon of the acetic anhydride, forming an ester linkage while releasing acetic acid as a by-product.
### Problem 2
**Reactants:**
- Two equivalents of aniline are reacted with benzoyl chloride.
**Explanation:**
- This reaction suggests the formation of an amide. Aniline acts as a nucleophile, attacking the carbonyl carbon of benzoyl chloride, leading to the release of hydrochloric acid and the formation of an N-phenylbenzamide product.
### Problem 3
**Reactants:**
- A primary amine (N-methylpropylamine) is reacted with glutaric anhydride in the presence of para-toluenesulfonic acid (TsOH).
**Explanation:**
- The amine can act as a nucleophile, attacking one of the carbonyl carbons in glutaric anhydride. This can lead to the opening of the anhydride ring and the formation of an amide with a carboxylic acid by-product.
### Note on Diagrams:
Each reaction involves organic molecules, oxygen and nitrogen groups, and catalysts. Detailed step-by-step mechanisms are typically shown in organic chemistry studies to illustrate electron movement, intermediate states, and final products.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F41fd932d-13b9-4832-9722-a6b60300bf08%2F84d4b123-eec4-4dc6-9715-1e4d6da59f92%2Fepf00ur_processed.png&w=3840&q=75)
