When we cut an onion, the synthase enzyme converts the amino acid sulfoxides of the onion into which acid?
Show answer & explanation
Correct answer: D
Explanation
The correct option is option 4 i.e. Sulfenic acid.
| Sulfenic acid | Lachrymatory-factor synthase is released into the air when we cut an onion. |
| The synthase enzyme converts the amino acids sulfoxides of the onion into sulfenic acid. The unstable sulfenic acid rearranges itself into syn-propanethial-S-oxide. | |
| Syn-propanethial-S-oxide gets into the air and comes in contact with our eyes. |
