Propylcysteine sulfoxide

Garlic also contains S-propylcysteine-sulfoxide (PCSO) and S-methylcysteine-sulfoxide (MCSO). PCSO can generate over 50 compounds depending on temperature and water content. The action of allinase on the mixture of alliin, PCSO, and MCSO can produce many other molecules, including allyl methane thiosulfinate, methyl methanethiosulfinate, and other mixed or symmetrical thiosulfinates (R-S-S-R ), where R and R are methyl, propyl, and allyl groups. 

Like garlic, onion contains many organic sulfur compounds, including trans-S-(l-pTO-penyl) cysteine sulfoxide, 5-methylcysteine sulfoxide, 5-propylcysteine sulfoxide, and cy-...
