Teacher dropped a competition between akpors and his friend isaac. Why chopping onions makes u cry n how to prevent it... So isaac was the first person to answer the question isaac: onion contain the amino acid, sulfoxide. When u cut the onion, the cells break and release the amino acid which is converted to sulfenic acid by the enzyme, lachrymatory-factor synthase. Sulphenic acid rearranges itself to form syn-propanethiol S-oxide which reacts with the water on ur cornea to produce sulphuric acid. The burning sensation produced by sulphuric acid stimulates the lachrymal gland to produce tears to remove the irritant. Chill the onion b4 cutting to inactivate theenzymes or chop it underwater to prevent tears. you can also wear protective glasses. Akpors ran away!
