In laboratory,Sudan IV is used to test for the presence of hydrophobic substances in food.Which organic molecule would exhibit a positive reaction with Sudan IV?
A)Lipids
B)Nucleic Acids
C)Carbohydrates
D)Globular proteins

Question

Quizplus · Accepted Answer

Sudan IV is a dye that specifically binds to hydrophobic substances such as lipids. Lipids are organic molecules that are characterized by their hydrophobic nature, which makes them an ideal target for Sudan IV. Nucleic acids, carbohydrates, and globular proteins do not have the same level of hydrophobicity as lipids and would not exhibit a positive reaction with Sudan IV.
