whenever Priya's grandmother cuts the onion, it makes her cry. once suggested them to cut the onion in water or under the running water to avoid irritation response. he told as we cut the onions it's cells are broken which allow enzymes to break down the acids and make us cry. (a) which type of value is explored by priya's uncle
Answers
Answer:
Enzyme that makes you cry—crystal structure from lachrymatory factor synthase from Allium cepa.
Answer:
Onions produce the chemical irritant known as syn-propanethial-S-oxide. It stimulates the eyes' lachrymal glands so they release tears. Scientists used to blame the enzyme allinase for the instability of substances in a cut onion. Recent studies from Japan, however, proved that lachrymatory-factor synthase, (a previously undiscovered enzyme) is the culprit (Imani et al, 2002).
The process goes as follows:
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-ropanethial-S-oxide.
Syn-propanethial-S-oxide gets into the air and comes in contact with our eyes. The lachrymal glands become irritated and produces the tears
