Question

Compare the antioxidants, what is similar about their bonding patterns? 

**Title: Structures of Antioxidant Molecules** The structures of several antioxidant molecules are shown below. Use these structures to answer Question 5. 1. **β-carotene (in carrots):** - Structure: Long chain with alternating single and double bonds, ending in two identical cyclic groups with additional methyl (CH₃) groups. 2. **Chlorogenic acid (in coffee):** - Structure: Complex molecule with a central cyclohexane ring, hydroxyl (OH) groups attached, an ester linkage, and an aromatic ring with an additional hydroxyl group. 3. **Melatonin (in olive oil):** - Structure: Contains an indole ring (a benzene ring fused to a pyrrole ring), linked to an acetamide group, and additional methoxy group (CH₃O) at the aromatic ring. 4. **Lycopene (in tomatoes):** - Structure: Long linear chain similar to β-carotene, characterized by consecutive alternating single and double carbon-carbon bonds, ending in two non-cyclic branched groups. **Question 5:** Examine the bonding patterns of the antioxidant molecules shown above. Do you notice any similarities? Describe any common bonding patterns you see. **Discussion:** - Look for similarities such as the presence of conjugated systems (alternating single and double bonds), presence of hydroxyl groups, aromatic systems, or patterns of methylation. - Consider how these patterns might contribute to their antioxidant properties.
