Question
Identify the compounds that are brightly colored-what are these colors? 1 Curcumin - yellow root of turmeric Curcumin - red root of turmeric Capsaicin - red powder Sucralose- dark red-brown Amoxicillin - pink solid Fluorescein - aqueous solution is fluorescent green Identify all substances that are used in medicine as antibiotics or in combination with antibiotics. Cocaine Aflatoxin B1 Guanosine Ciprofloxacin Amoxicillin Zoloft Identity all the compounds that are known to be highly toxic to humans- where might one encounter these substances and what kinds of toxic effects are attributed to these substances? Aflatoxin B1 - puffer fish - carcinogen Aflatoxin B1 - peanuts, grains - carcinogen Tetrodotoxin - peanuts, grains- carcinogen Tetrodotoxin - puffer fish- neurotoxin Methyl jasmonate - jasmine flowers - carcinogen Allethrin - chrysanthemum flowers - neurotoxin Identify all of the molecules that are achiral. Capsaicin Tetrodotoxin Fluorescein Curcumin Sucralose CiprofloxacinExplanation / Answer
1. Curcumin is a bright yellow colored compound present in turmeric, capsaicin is the compound that is
present in red peppers, Sucralose is a sugur substitute which is white, Amoxicillin is an anti bacterial
and it is pink compound, Fluroscein is actually orange / red compound, but its aqueous solution under UV
light exhibits fluroscent green.
1,2 and 6 are bright colored.
2. Cocaine is anesthetic but not antibiotic, aflatoxin B1 is used in making antibiotics,
Ganosine is combined with antiobiotics (binding site for anti-biotic). Ciprofloxacin is an antiobiotic
used to treat against bacterial infections in children. Amoxicillin is Pencillin antiobiotic.
Zoloft is an anti-depressant
2,3,4,5 are anti biotics
3. Tetradotoxin is a poison found in the internal organs of Puffer fish and that damage nerve tissues
Aflatoxin B1 is present in milk, peanuts, cheese etc and it is carcinogenic. Methyl jasmonate
is a potential compound used in cancer therapy, it is not a carcinogen. Allethrin is not neurotoxin
it is harmless to humans and used as insecticide.
2 and 4 are highly toxic.
4. achiral molecules have super-imposable images, Fluroscein and Curcumin are achiral rest are chiral
