Methionine
Methionine is a sulphur-containing amino acid, like cysteine. Most cereals are rich in methionine, while legumes contain only low levels of it, whereas the opposite is true of lysine. The word 'methionine' is derived from 'methyl', for the hydrocarbon radical, CH3, and 'thio-', for sulphur.
