Question

Match list I with List II
List I (Amino Acids): A. Histidine, B. Lysine, C. Tyrosine, D. Ornithine
List II (Biogenic Amines): I. Cadaverine, II. Histamine, III. Putreseine, IV. Tyramine
Choose the correct answer from the options given below:

• A. A-IV, B-III, C-II, D-I
• B. A-IV, B-III, C-I, D-II
• C. A-II, B-I, C-IV, D-III
• D. A-II, B-I, C-IV, D-III

Hint:

Biogenic amines are not only foul-smelling but can also be toxic. Histamine is the most famous because it causes allergic-like "Scombroid" poisoning.

Answer 1

The Correct Option is C

Step 1: Understanding the Question:
This question deals with the formation of Biogenic Amines through the bacterial decarboxylation of free amino acids in spoiling fish.
Detailed Explanation:

• A - Histidine: Decarboxylation of Histidine produces Histamine (II). This is critical in Scombroid poisoning (Tuna, Mackerel).

• B - Lysine: Decarboxylation of Lysine produces Cadaverine (I), named for its foul "corpse-like" odor.

• C - Tyrosine: Decarboxylation of Tyrosine produces Tyramine (IV).

• D - Ornithine: Decarboxylation of Ornithine produces Putrescine (III).

Step 2: Final Answer:
The matching is A-II, B-I, C-IV, D-III. This corresponds to Option (C).
