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.
![**Title: Understanding Acid-Base Equilibria in Organic Chemistry**
**Objective:**
Determine the missing structures in acid-base equilibria reactions.
---
**Problem Statement:**
In the given acid-base equilibrium, identify the structure of the missing substance(s).
**Reaction:**
\[ \text{H}_3\text{C}\overset{\text{CH}_3}{\underset{\text{|}}{\text{C}}}\overset{\text{|}}{\text{NH}_2} + \text{H}_2\text{O} \rightleftharpoons \text{H}_3\text{C}\underset{\text{|}}{\overset{\text{CH}_3}{\text{C}}}\overset{\text{|}}{\text{NH}_3}^{+} \; + \; ? \]
**Diagram Explanation:**
1. **Chemical Structure:**
- Left side: A benzene ring with two attached methyl groups (CH₃) and an amino group (NH₂).
- Right side: The same benzene structure with the amino group gaining a proton, becoming NH₃⁺.
2. **Reaction Type:**
- **Acid-Base Reaction:** The amino group acts as a base and accepts a proton from water, generating the H₃O⁺ (hydronium ion), which is the missing structure.
**Tool:**
Utilize the interactive ChemDoodle sketcher tool to draw methyl (CH₄) structures or any other required organic structures to further analyze and visualize the equilibrium.
**Key Learning Points:**
- Recognizing functional groups in organic compounds and their behavior in acid-base reactions.
- Understanding how protonation affects molecular structure and charge.
- Practicing the use of chemical drawing tools to represent organic molecules visually.
